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.

The creature hatches as a Hedgehog but you named it Pebblecrab. The Buddy name lives on. The hunger is new.

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.
