Twinkle/Bonus Stages

Besides the forty regular stages and ten extra stages, there are fifteen different bonus stages, which contain bonus items (pairs of cherries, hamburgers, strawberries, eggs, bombs, pairs of sunglasses, helmets, pocket watches, winged sneakers, roller skates, and extra lives); unlike the normal stages, it is impossible to lose any lives on bonus stages, because there are no enemies in them, and even if the timer on one should run out before both Pac-Mans have managed to eat every bonus item on it between them, they shall not lose a life (instead, they will merely proceed to the game's next normal stage).

The bonus stages shall be invoked after both Pac-Mans clear any regular stage by only eating all the regular pellets between them; this means that they cannot eat any bonus items (or power pellets, as unlike in the official Pac-Man games, they do not have to be eaten to clear the stages) or the game will just proceed to its next normal stage (as usual). For the third, fourth, ninth, tenth, thirteenth, fourteenth, fifteenth, seventeenth, nineteenth, twenty-fourth, twenty-fifth, forty-second, forty-sixth and forty-seventh stages, there are also large red pellets that immediately clear the stage and invoke a bonus stage when eaten (even if both Pac-Mans had eaten some or all of the bonus items on those stages between them, and some of them feature more than one).

Bonus Stage 1
This maze contains 9 helmets, 20 eggs, 5 pairs of cherries, 10 hamburgers, 7 winged sneakers, 10 strawberries, and a time of 23 seconds; in addition to those, there is also a hidden extra life, which can be revealed by eating two helmets to make it become a solar helmet and firing a shot at the south wall.

This bonus stage appears if you clear the following stages without eating a bonus item: first stage, sixteenth stage, thirty-first stage, and forty-sixth stage (it's also possible for you to immediately clear the forty-sixth stage and qualify for it, even if you've consumed a bonus item, by eating its large red pellet).

Bonus Stage 2
This maze contains 28 eggs, 35 pairs of cherries, and a time of 30 seconds; there are also four invisible holes in the walls that are surrounding the eggs.

This bonus stage appears if you clear the following stages without eating a bonus item: second stage, seventeenth stage, thirty-second stage, and forty-seventh stage (you may also immediately clear the seventeenth and forty-seventh ones and qualify for it, even if you have eaten a bonus item, by eating their large red pellets); on stages which feature more than one large red pellet, you will also only have to eat one of them to immediately clear the stage.

Bonus Stage 3
This maze contains 2 helmets, 2 winged sneakers, 8 eggs, 1 extra life and a time of 20 seconds; to get to the first winged sneaker, you must eat both (or one, if your Pac-Man still has one) of the helmets to make it become a solar helmet and fire a shot at some of the blocks to destroy them before its effect wears off, and to reach the eggs and extra life, you must already have the ability to jump on eating that first winged sneaker for it to become a high jump.

This bonus stage shall appear if you clear the following stages without eating a bonus item: third stage, and eighteenth stage (you may also immediately clear the third stage and qualify for it, even if you have eaten a bonus item, by eating its large red pellet, and that stage is the first one that features one).

Bonus Stage 4
This maze contains 2 bombs, and a time of 22 seconds; besides those, there are also 24 hidden strawberries and 22 hidden hamburgers, and they may be revealed by eating either bomb (however, once one of the bombs has been eaten, the other one shall not have any effect, except for the 200 points).

This bonus stage shall appear if you clear the following stages without eating a bonus item: fourth stage, nineteenth stage, thirty-fourth stage, and forty-ninth stage (if you manage to reach the secret stages and qualify for it after clearing the forty-ninth one, it will also be the last one you see in the game); it's also possible to immediately clear the fourth and nineteenth stages and qualify for it, even if you eat a bonus item, from eating their large red pellets.

Bonus Stage 5
This maze contains 4 helmets, 2 extra lives, 10 eggs, 2 winged sneakers, 2 wormholes, and a time of 17 seconds; besides those, there's also a hidden bomb, and it can be revealed by eating two (or one if your Pac-Man still has one) of the helmets to make it become a solar helmet, going into the lower wormhole from the south to come out of the upper one facing the north wall, then firing a shot at it to destroy it before the L-meter runs out. After eating the bomb, you can get to the extra lives, eggs, and winged sneakers - however, if the L-meter should run out after you have eaten all four helmets, and you have not managed to reveal and eat the hidden bomb by that point, there is no way that you can get to the extra lives, eggs, and winged sneakers.

This bonus stage shall appear if you clear the following stages without eating a bonus item: the fifth stage, the twentieth stage, and the thirty-fifth stage.

Bonus Stage 6
This maze contains 10 pairs of cherries, 13 winged sneakers, 11 hamburgers, 13 eggs, 10 roller skates, 11 helmets, and a time of 17 seconds; the items are also arranged to spell out the name of the manufacturer, SemiCom (like those on the first bonus stage were arranged to spell out this game's name).

Bonus Stage 7
This maze contains: 32 eggs, 12 strawberries, 1 extra life, 1 pair of sunglasses, 3 pocket watches, 1 bomb, and a time of 12 seconds; to get to the eggs, strawberries and extra life, it is required to eat the bomb (and all three pocket watches, as there would not be enough time to eat all the items otherwise).

This bonus stage shall appear if you clear the following stages without eating a bonus item: the eighth stage, twenty-third stage, and thirty-eighth stage.

Bonus Stage 8
This maze contains 24 pairs of cherries, 16 hamburgers, 8 strawberries, 1 bomb and a time of 27 seconds; besides those there are also 40 hidden eggs, and they can be revealed by passing through the invisible hole in the top of the wall which surrounds all of the "non-hidden" items, then eating the bomb.

This bonus stage shall appear if you manage to clear the following stages without eating any of the bonus items: the ninth stage and twenty-fourth stage; it's also possible to immediately clear both these stages and qualify for it, even when you have eaten a bonus item, through eating their large red pellets.

Bonus Stage 9
This maze contains 57 pairs of cherries, 1 extra life, and a time of 25 seconds; there is also a hidden path in the top of the wall surrounding the extra life.

This bonus stage will appear if you happen to clear the following stages without eating any of the bonus items: the tenth stage and the twenty-fifth stage; it's also possible to immediately clear both these stages and qualify for it, even when you have eaten a bonus item, through eating their large red pellets.

Bonus Stage 10
This maze contains 2 extra lives, 2 pocket watches, and 1 bomb, but a time of 0 seconds (possibly a bug); this means it is impossible to reach the items.

Bonus Stage 12
This maze contains: 34 pairs of cherries (plus 20 hidden ones, making a total of 54 pairs), 26 strawberries, 12 eggs, 1 helmet, and a time of 17 seconds; the hidden pairs of cherries can be revealed if your Pac-Man already has a helmet on eating this stage's one for it to become a solar helmet, then fires a shot at some of the blocks in all the walls to destroy them before its effect wears off (the ones in the north and west walls are also outlined in red below).

This bonus stage will appear if you clear the following stages without eating a bonus item: the thirteenth stage, twenty-eighth stage and forty-third stage; it's also possible for you to immediately clear the thirteenth stage and qualify for it (even if you've eaten a bonus item), through eating its large red pellet.

Bonus Stage 13
This maze contains 56 bombs, 23 eggs, 7 pairs of cherries, and a time of 17 seconds; the bombs also don't have any effect apart from the 11200 points.

This bonus stage will appear if you clear the following stages without eating bonus items: the fourteenth stage, twenty-ninth stage and forty-fourth stage; it's also possible for you to immediately clear the fourteenth stage and qualify for it, even if you've eaten a bonus item, through eating its large red pellet.

This maze contains 12 strawberries, 52 pairs of cherries, 12 eggs, 1 extra life, and a time of 30 seconds; there is also a hidden path in the north wall that you shall have to follow through the west wall and off the left side of the screen in order to come out on the other side of the screen and eat the extra life.

This bonus stage will appear if you manage to clear the following stages without eating any of the bonus items: the fifteenth stage and the thirtieth stage; it's also possible for you to immediately clear the fifteenth stage and qualify for it, even if you have eaten a bonus item, through eating its large red pellet.

This bonus stage shall only appear if you manage to clear the twenty-second stage without eating any of its bonus items (so it is the rarest in the game).

Exceptions
There are eight exceptions in which a bonus stage may not be invoked: on the seventh, thirty-third, thirty-seventh, thirty-ninth, forty-fifth and forty-eighth stages, it is impossible to not eat any bonus items because of their respective maze setups, while the fortieth stage shall not invoke a bonus stage even if both Pac-Mans clear it by only eating all its regular pellets between them (on account of the fact that it is the final regular stage, but an instant clearing of that stage by eating the ice cylinder after you have found the way to it shall not invoke a bonus stage either), and finally, the fiftieth stage will also not invoke a bonus stage even if both Pac-Mans clear it by only eating all its regular pellets between them (because of the fact that it is the true final stage).
