S-A-I-N-T Prototype Number 3) is one of the five prototype military robots proposed by Nova Laboratories.
When Number 3 and its brothers were set loose on Number 5, the sentient robot uses his smarts to outwit them. After already dealing with Number 1 and Number 2, Number 3 repeatedly fires its laser at Number 5, whose only defense against it is a rock until the robot leads Number 3 crashing into an outhouse.
After being shut down, Number 3 is then reprogrammed into acting more like Jerome "Curly" Howard of the Three Stooges. Number 3 is also given a toilet seat from the same outhouse it had crashed into, which is worn around its neck, and the top part of its helmet is taken off, to look like Curly's shaved head.
