Actually I think its one of the white zombies that drags in the white chick.
Anyways, I have a question. I beat the game. i got all the medallions. And yet the game didn't unlock all of the secrets that should have been unlocked. I checked my achievements and it said out of all the levels I played, the ONLY one i didnt beat was 5-3. Did anyone else get this glitch or know why that would happen? The game also didnt give me the achievment for beathing the game on normal yet I got the achievment for beating both bosses in 5-3 as well as for beating 6-1 through 6-3
