I hope my pictures are good enough, because this one’s really spectacular. Crease Pattern Challenge #60 is KAPPA the Water Imp by Chuya Miyamoto.
He has a lanky, nearly simian body, webbed fingers, the head dish, scraggly hair, the beak, cute eyes, and an amazing shell. I’m afraid it’s gonna be hard to see in the bright green I used.
The shell is pretty cool. Below, I have the unfinished shell first. This version is how it’s given in the crease pattern. It could be a mess to show the finished version in the pattern, but it’s clear from the cover and other images. You sink each point in and out a few times to make concentric scutes (the shell sections; yes, I had to look that up).
Also notable: He is very head and shell heavy. If you make him, his legs almost certainly won’t hold him up, so, if you don’t want him sitting, either his legs should be reinforced or he should have some other structure to hold him up.
