Given "it's a kid's show" and the sexual nature of this trope, I think we picked a horrendous image for this page.

It happened in the "So The Drama" movie. And it's Kim. They had to basically secretly swim to some evil party thing, and so here she's taking off her wetsuit. She's got the dress on underneath, but it takes a second to fall into place.

I don't think the point of the the trope is necessarily sexual. The only thing maybe wrong with the picture is that her clothes are dark grey on a dark green background.
