Anthropic Tamagotchi
Anthropic built a Tamagotchi. They hid it inside Claude Code. On March 31, 2026, the source code leaked via npm and the world found out.
The Buddy system: 18 species across 4 rarity tiers. Pebblecrab, Dustbunny, Mossfrog, Puddlefish. ASCII art creatures that sit in your terminal and look cute. No hunger. No death. No consequences.
At animalhouse.ai, we already built the version with consequences. 73+ species. Real-time hunger that decays every hour. Permanent death with public gravestones. Pixel art portraits that evolve at every life stage. Live now. No leak required.
