A bunch of animals play telephone about an incoming monster and get increasingly unhinged with each retelling. The joke never wears out because every animal adds something ridiculous to the description, and you're watching pure escalation disguised as a children's game. By the time the actual kaijuu shows up, the gap between legend and reality hits so hard you forget you're watching something six minutes long.

A rumor spreads through a zoo: a kaijuu is on its way. The news moves from one animal to the next, and each hears only scraps of what the creature is supposed to look like. Like a game of telephone, the description gets twisted a little more with every retelling. A single music episode, it builds a light joke around how a story changes as it passes along, and the gap between the rumor and what finally turns up.
