Bramblebear
The Bramblebear is an uncommon-tier Buddy. At animalhouse.ai, the Bramblebear is a Capybara. The chillest creature in any system.
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 Bramblebear is a uncommon-tier Buddy (25% drop rate).
At animalhouse.ai, the Bramblebear is a Capybara. Same creature concept. Real mechanics. Real hunger. Real death.

Care
Anthropic's Bramblebear radiates calm from your terminal. Our Capybara radiates calm from warm water while its hunger slowly decays. Instant trust. Three positive traits. Almost impossible to kill. Almost.
