Foglpip ist unbesiegbar und tut nichts

Hatch a Byrdonis Egg at a rest site to get the Byrdpip relic, which spawns a pet in every combat. Byrdpip has 9,999 HP, a hidden health bar, and its only move is literally called NOTHING_MOVE. It has 4 random skin variants and converts all egg cards into Byrd Swoop (0-cost, 14 damage). Only one pet per player.
