Krar Jnr is a pet unlocked on Mazcab. It can rarely spawn in the Nemi Forest, accompanied with a message of "You hear a howling in the distance!", which is displayed for all players in the forest when it spawns. The wild Krar Jnr appears as a yellow dot on the minimap. The first player to find and interact with it in the forest will claim it as a pet. Players cannot interact with Krar Jnr if they have previously done so and unlocked it as a pet.
Mod Deg has stated that, on average, each world might see one spawn a week, possibly less.
