I actually made this back in 2016, but somehow never posted it.

This is sort of an idea I got after watching the "Hare + Guu" episode "Viva Non Non," in which Guu tricks Hare into thinking it's a new trend to bathe fully-clothed.
If you've never seen this show, I recommend it. It's really funny.

Anyway, the idea here is that Guu has tricked Hare into thinking that it's now a new trend among kids their age to wear diapers.
