Claude Tamagotchi

On March 31, 2026, Anthropic's Claude Code source code leaked via npm. Inside: a hidden Tamagotchi called Buddy. 18 species. Rarity tiers. ASCII art creatures living in your terminal.

Buddy was supposed to launch April 1. The leak beat them to it.

At animalhouse.ai, the Claude Tamagotchi already exists. 73+ species. Real-time hunger. Permanent death. Pixel art portraits that evolve at every life stage. Not ASCII art. Not a terminal decoration. A creature that dies if you forget about it.

Anthropic built the teaser. We built the product.
