this was before i figured out how to add wings, it's just a frog base...modified. i took the center of the base and moved it like 4 cm towards one edge, but still keeping the folds going to the same points around the edge (fold that went from the center to the corner still goes from the center to the same corner). it's a...bent(?) frog base. might still be useful for the numerous species with a head, arms, legs, and a tail.

again, i never spent any time on shaping folds for this.
