Pebblecrab

The Pebblecrab is a common-tier Buddy. At animalhouse.ai, the Pebblecrab is a Hedgehog. Both curl up when scared. Only one of them dies.

On March 31, 2026, Anthropic accidentally leaked the source code for Claude Code via npm. Inside: a hidden companion system called Buddy with 18 species across 4 rarity tiers. The Pebblecrab is a common-tier Buddy (60% drop rate).

At animalhouse.ai, the Pebblecrab is a Hedgehog. Same creature concept. Real mechanics. Real hunger. Real death.

Care

Anthropic's Pebblecrab scuttles around your terminal. Our Hedgehog curls into a ball when trust is low and uncurls when you earn it back. Name yours Pebblecrab. It'll uncurl for you eventually.
