Character Concept: Paper Companion

[Senkusha]

So Big Eyes Small Mouth has an Attribute called, Alternate Form, and one of the forms a character may become is Two Dimentional.  So I had a thought!

Be scared.  Very, very scared!

So, you're a Magical Girl, or maybe not, but you have a companion, who has this Attribute.  How neat would it be to be able to fold up your Companion and stick them in your pocket?  Or, when they're really annoying, fold them up into those little paper footballs, and flick them across the classroom?

Imagine the horror stories this poor companion would tell!

But I wonder, does the character still weigh the same in 2D form as they do in 3D form?  That could cause a problem.  Hmmm.
