LazyTown had actors in makeup to make them look kind of like action figures. The girl was very pink. The guy wore blue with a bandana that I could see thinking was a sailor through the nostalgia goggles. One episode had remote controlled shoes that made people dance.
You can also check the Involuntary Dance page but that was the closest one I could find.
This signature says something else when you aren't looking at it.Sounds like it could be Zoobilee Zoo. There is some tumbling in the opening sequence, and the costumes sound like what you described. The pink cat girl is apparently supposed to be a kangaroo, but I agree that she looks like a cat. https://www.youtube.com/watch?v=oowOsEOTApA

I'm trying to find a live-action kids tv series or show I used to get from the library on VHS. It had four or five main characters that were sort of anthropomorphic people in makeup. The girl one was pink and maybe sort of catlike. The main things I remember is that in the opening sequence one of them cartwheeled, one was this pink cat girl and another was a sailor, and there was an episode which a "red slippers" storyline where the pink one got these magic red slippers so she could dance even better but then she could stop dancing. I've been trying to find this for years, please help!
