Mappy Arrangement/Rounds 22-25

Round 22
The twenty-second round contains fifteen platforms, two regular doors (one of which has a knob on both sides), a singular power door, three levers, four regular trampolines, four Mewkies and two bells; the animated background for this (and the next three) rounds is also identical to that for the twelfth one.

Round 23
The twenty-third round (which has a different attic to the twenty-second one) contains ten platforms, two power doors (both of which have knobs on both sides), six levers, three regular trampolines, four Mewkies and two bells; this is also the last regular round in the game with five cats, but as there are no power doors in the next one, the point value for catching six cats in a microwave emitted by one (that Nyamco would, of course, double) isn't applicable.

Round 24
The twenty-fourth round contains ten platforms, two regular doors (both of which have knobs on both sides), seven levers, four regular trampolines, and five Mewkies; the mice can also break the trampoline between the third-level platforms if they have to. After clearing this round, it will be time for Mappy and Mapiko's second fight against Mecha-Nyamco - and this time, he can fly up to the platforms they are standing on, to launch groups of five Gosenzo in a straight line over their heads (he also takes nine hits before glowing red and flying faster this time, and eight more before exploding a second time).

Round 25
The twenty-fifth (and second boss) round is identical to the twelfth one (only Mecha-Nyamco takes seventeen hits); when Mecha-Nyamco 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, again, launch groups of five Gosenzo at the mice (this time by flying up to the platforms they are standing on to launch them over their heads), so when he does, you'll have to avoid using the trampolines - and this time, he shall only glow red and start flying faster after he has been hit by nine microwaves. After Mecha-Nyamco has been hit by eight more microwaves, he will explode (if either mouse is in mid-air at that point, he shall again get frozen there) and disappear as the mouse who delivered the final microwave receives 10000 points; both players shall now receive a "Stock Bonus" of 100000 points for every life they have remaining, a "Pairing Bonus" of 1000000 points if they had collected all the items on the regular rounds in pairs and in ascending order of point value (but that is extremely difficult to do), and a "Non Hurry Up Bonus" of 100000 points for every regular round they cleared before the text of "HURRY" flew across the screen.
