Petrock | ペットロック

Petrock(Pet/Maskota + Petra + Rock/Roca)
ペットロック(ペット + ロック/岩)
The various minerals it eats are used to create a tough rocky shell around its soft squishy body and organelles. It has many dog-like behaviors and tends to act like a loyal and kind pet. In the rare situation where it gets aggressive or needs to defend itself, it will perform a powerful jab with its horn.
