So you killed a zombie and it got stuck in a pile of rubble or wreckage. Maybe you brought down a house on a few of them. Good riddance.
A day has passed.
Oh boy. There’s that impromptu burial spot again. Wait. What’s making that noise? WHOA! That’s… abnormal.
Slow and extra noisy. These guys are full of debris! Could turn into something nasty if they get the time to mutate. Don’t hurt yourself trying to bring these bumbling resource-ridden monstrosities down. Sharp edges.
