I mean, they're decaying and becoming less organised, but they still put some energy into being undead and staggering around. And then there's the fungus. Surely that's putting some energy into making their green-ness more uniformly green?

I'd imagine that the fungus would largely survive off fat reserves, with occasional added BRAAANZ when it gets a kill.
