[Origami] Variations on a classic

[Dawn Tucker via Origami]

I'm looking for inflatable variations on the water bomb model. I have the 
rabbit, goldfish, stellated octahedron, chick, and snail with water bomb shell. 
(Jeremy Shafer's heart model inflates, but has a different folding sequence.) I 
know I've seen at least one other, but I can't remember what it was. What else 
is just a little different from the water bomb, and is also inflated to 
complete?
Thanks in advance! I always appreciate your help!
