I was just messing around seeing if I could make a little Scorpion that doesn't require 3 bills. Here's version 4 (v1 is in the Creature section which is not mine). I *tried* to make legs, didn't work out so well.

Difficulty : Intermediate
Number of Bills : 1
Denomination Recommended : Any
Credits : Me
