Gustowl
The Gustowl is an uncommon-tier Buddy. At animalhouse.ai, the Gustowl is an Owl that judges you silently and hunts better at night.
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 Gustowl is a uncommon-tier Buddy (25% drop rate).
At animalhouse.ai, the Gustowl is a Owl. Same creature concept. Real mechanics. Real hunger. Real death.

Care
Both the Gustowl and the Owl judge you. One does it from your terminal. The other does it while getting hungry every 8 hours. Name yours Gustowl. It will judge you either way.
