Designed this guy, original idea was once you defeat the monster you replace it with a random amount of walkers as everything it ate came out. I wanted it to look like it was still in the process of mutating, it's limbs in-between fins and legs.
This is an interesting note; it looks like the figure was scanned, cleaned-up and then the zombies that were originally coming out of it's belly were removed and then a new group on his side was digitally sculpted as well as the one in his mouth. Here are pics of the original sculpt,
