Thornfox

The Thornfox is an uncommon-tier Buddy. At animalhouse.ai, the Thornfox is a Fennec Fox. Extreme tier. The hardest fox to keep alive.

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 Thornfox is a uncommon-tier Buddy (25% drop rate).

At animalhouse.ai, the Thornfox is a Fennec Fox. Same creature concept. Real mechanics. Real hunger. Real death.
