Yukkuri and Cow
A pair of yukkuri siblings go to the river to drink, but one of them gets stepped on by a cow in the river. The remaining yukkuri informs her parent that a big monster stepped on its sibling, and the parent puffs up in response. However, the child keeps saying that the monster is bigger, so Marisa continues to suck in air... until it explodes.
