So... if a Horror hound comes from a recently deceased hound brought back to life, and we can probably assume that the moonrock pengulls have the same backstory since the pengulls would probably very well not survive a sudden change in their body that the mutation causes, Does that mean the fact that the deep depths of the constant's ocean are filled with dead or starved pengulls that ressurect on the lunar island giving a reason why there extremely hostile the moment they spawn?

This Is a way to help explain my theory/point...(sorry it's a really bad picture, I dont have any more paper to do this on)
