"Did someone remember to remove the add on from the cake slice?"
A living pizza slice with boxing gloves and glasses to see. If they punch you, you will be stunned.
When a survivor found a Cake Slice, he brought it home with him, but accidentally put it in the oven with a slice of pizza. When he opened the oven, this abomination came out. King Cheese eventually took it, made more of it, and used them as his minions.
Avoid getting hit by it because you will get tripped and be stunned.
