Most of the characters in the show wear no clothes at all or just a few accessories, but they are animals, so there's nothing inappropriate. Out of the main characters Mundi is the only one who wear full clothes at all times, because of her more human-like appearence.

In the episode "A Twister Tale", Anabella kisses one of the side characters. (The side character in the episode is named Luke.) Anabella is canonically a 5 year old girl, and Luke is most likely an adult.

Very mild slapstick.

Nothing really scary, it's a very family friendly show.
