Like I said, it's my first one so it has some problems, but I hope it can be folded!
Tissue foil or wet folding works well with this one, as it will be a 3D model.
The belly is also color-changed, so you can use a duo-color paper too!
Thanks to ftamgdude55 for getting all 3 pages to one, here is a link to the diagram:

Finished model:

If you have any problems with the folding or the final shaping, don't be afraid to ask, I'll help you
PLEASE fold it, and post results!
