Playful penguin

Introduce a small ally for encounters in the ice caves. - Features: A penguin that taunts enemy creatures by sliding across the ice and drawing their attention for a few seconds. - It can be tamed by the player using fish though, much like cats, it puts up a bit of a fight, sliding around and trying to get away. - Ability: Much like axolotls, if necessary, the penguin will retreat to regenerate both its own and the player's health, while also providing a minor resistance effect against freezing. A great excuse to add penguins to the game and have them help us out in a chaotic environment.
