Wheel chair zom should be fairly rare. But also can it sport some neat items by default:
-a pistol with a spare clip of bullets(ex-military?)
-Oxygen tank, because elderly people sometimes have these on back of chair.
Toddlers may not have teeth and should give a debuff for killing like the other kids? They may not bite but could slow you by grabbing your ankles.
I actually think of the zombie children as toddlers. I don’t know if that was what’s intended. But I hear ‘Snot Gobbler’ and assume it’s a three year old.
I made a zombie fetus in one of my mods before realizing how pointless it was. It just lays there.
The only other idea I have for zombies is to split all zombies into ♂ and ♀ variants, so you know at a glance whether the thing is male or female. I don’t think anyone cares about that except for roleplayers and possibly youtubers.
