Animated how?

The head is probably a moving platform. You can make those in this new stage builder, you can even customize
the movement path.

Precisely!

I thought so. Apparently the new stage builder also allows you to work in layers, making parts of a stage purely decorative.
As en example, i would imagine that on this stage that you made that one of renamons ears is in the foreground layer, and
the other is in the background, allowing fighters to pass between them.

Believe it or not, i haven't even gotten to try the new stage builder yet, as i don't own the game. I will own it soon though,
very soon...

Copyright issues? Seems like another Mario 1-1 in Little Big Planet type-thing.
