Mappy Arrangement/Rounds 9-13

Round 9
The ninth round contains: eighteen platforms, three regular doors, two power doors, two levers, five double-strength trampolines, four Mewkies, and one bell; catching five cats in a microwave emitted by a power door is also worth 3000 points (Nyamco will yet again double it), and if either mouse jumps up to (or drops down onto) the bell, it will, like those in the eighth through tenth rounds of the original Mappy, fall down off the bottom of the screen and stun all cats it hits on the way for a short period of time (the Mewkies, including the fatter one, are worth 300 points apiece, but Nyamco is worth 1000 points).

Round 10
The tenth round, which has a differently-arranged attic to the ninth one, contains seventeen platforms, three regular doors, two power doors, two levers, six double-strength trampolines, one regular trampoline, four Mewkies, and two bells; the mice can also break the regular trampoline if they have to, but it will regenerate after they land on the double-strength one below it, to prevent them from bouncing back up to either of the platforms it is connected to.

Round 11
The eleventh round, which is the first regular one without double-strength trampolines, contains sixteen platforms, four regular doors, two power doors, three levers, five regular trampolines and four Mewkies; after clearing this round, it'll be time for Mappy and Mapiko's first fight against Mecha-Nyamco.

Round 12
The twelfth (and first boss) round contains twenty-five platforms, four rechargeable power doors, six infinite-strength trampolines (which will not award you 10 points every time you jump on them), and Mecha-Nyamco (who, like the Gosenzo, can kill Mappy and Mapiko in mid-air); when he starts flying towards either mouse, they will have to walk under him, use one of the infinite-strength trampolines to bounce up to a platform that they can open one rechargeable power door from, and open it when he is in the line of the microwave it emits (however, regardless of whether the microwave hits him or not, you will immediately have to close the door again to recharge it). Mecha-Nyamco will also launch groups of five Gosenzo at the mice, so when he does, you'll have to stand somewhere where you know they will not hit them - and after he has been hit by four microwaves, he will glow red and start flying faster. After Mecha-Nyamco has been hit by five more microwaves, he will explode (if either mouse is in mid-air at that point, he shall get frozen there) and fly off the right side of the screen as the mouse who delivered the final microwave receives 10000 points; the game will then announce the third bonus round with the text of "BONUS ROUND. STING S IN TIME.". As with the first two it contains ten red balloons and one randomly-placed Nyamco balloon, and the mice will have thirty seconds to collect all eleven balloons between them, but some trampolines must once again be broken through to get some of them (however, one breakage can be avoided here, if either mouse moves to the left just before getting the ninth red balloon).

Round 13
The thirteenth round contains thirty-seven regular trampolines; after either mouse collects the fifth red balloon, they must both take the middle path, on which they must break a trampoline to continue through it (and, as mentioned above, unless either mouse moves to the left just before he collects that ninth red balloon, he will have no choice but to break another trampoline as a result of falling back down onto it when it is red). The dimmed images of the Nyamco balloon at the top of the map once again show where it may be placed, but if you accidentally take either, or both, of the wrong paths (the path above the trampoline you must break is also a dead end) and have to go back, it may not be possible to finish the round before the time runs out.

Once either mouse has collected the Nyamco balloon, the stars in the background shall glow; the text "EARNINGS" will then be displayed at the top of the screen as the balloons both players collected are displayed under their mice (they shall receive 200 points for every red balloon they collected and 2000 points for the Nyamco balloon). If Mappy (or Mapiko) collected all eleven of the balloons in a one-player game he will also receive a "PERFECT" bonus of 10000 points - however, in a two-player game, the mouse who collected the Nyamco balloon shall receive a "WIN" bonus of the same value.
