Commentary:

Maybe this isn’t Green’s pool, because I don’t think Yellow could keep him out of it otherwise. Red is not really a very good friend in these early comics. Yellow is just bullying his best friend right in front of him and he is ignoring it. Though I may have done that just because he is flipping over in the pool and that’s funnier than coming to his friend’s aid.

That pool doesn’t have a ladder. They should buy a ladder for it.
