As we all know from playing platformers, ice does strange things to the stage. In this case, the things done were very strange. You won’t find out how by reading the revision of Digimon Adventure episode 9, Clash! Freezing Digimon / Subzero Ice Punch, so I made some .gifs instead:
Agumon, too heavy to lift, is not so heavy that he breaks Taichi’s foot when kicked hard enough to launch several meters.
Taichi and Agumon may fall, but they cleverly steal the backwards momentum Yukidarumon needed to stop himself!
Mojyamon, from a standing position, majestically leaps into the air in a perfect arc several times his own height.
