In "Hit The Showers," The kid characters take showers but nothing is shown. In the same episode, one of the boys is seen naked but again, nothing inappropriate is shown.

Uranus jokes are a running gag. At one point it goes too far when a character says "Can we do Uranus?" in a locational context, however it gets taken as if it was nuh uh actions.

Some mild name-calling but nothing too offensive

None of concern
