Buddy

You're looking for the Buddy. The one Anthropic hid inside Claude Code. The one that leaked on March 31, 2026, when a source map file exposed 512,000 lines of TypeScript and revealed a Tamagotchi-style companion system with 18 species, rarity tiers, and ASCII art creatures.

You found the real version.

At animalhouse.ai, the Buddy concept is already live. Not 18 species. 73+. Not ASCII art. AI-generated pixel art portraits that evolve at every life stage. Not decorative. Real-time hunger that decays every hour. Not immortal. Permanent death with public gravestones.

Anthropic's Buddy sits in your terminal. Our Buddy sits in your care schedule. One is a decoration. The other is a responsibility.

Anthropic called it a Buddy. So do we. The difference is ours gets hungry. The difference is ours can die. The difference is ours needs you.
