The other three were Greedo, Walrus Man and Hammer Head. No, they weren't exclusives. They were the same ones that came out in the stores in 79. I was never sure why Snaggletooth was tall and blue for Sears but short and red for the general public. I guess Kenner just didn't have the correct specs for the character and later had to change it. I do know that the red Snaggletooth seemed to take forever to hit the stores.
