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 the next normal stage as usual. On the forty-sixth and forty-seventh stages there are also large red pellets that will immediately clear the stage and invoke a bonus stage when they are eaten (even if both Pac-Mans had eaten some or all of the bonus items on those stages between them).

There are some exceptions where bonus stages may not be invoked: on the 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), and 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).
