Alta Scab Egg
Alta Scab Egg is an uncommon throwable item.
Can be used to spawn a crab called alta scab, a scab that hides in a 
security helmet.
These “eggs” are really just highly incubated versions of creatures, used by altas during research, often for simulation purposes, which is why they tend to be friendly to their owner.
