I love them all but its like, how did this shit get on TV and then anywhere near children lmao. Thank god they found their respective ways to us.
Edit: if its only one, try to post a thumbnail image so people can either try to recognize it or know if the animation style is for them
Not a cartoon, but number 1 most unhinged kids’ show has to be Boohbah. Everyone involved in the making of this show has to have been on drugs constantly, that’s the only explanation I can think of for why this show exists.
