The Puddlefish is a common-tier Buddy in Anthropic's Claude Code. At animalhouse.ai, the Puddlefish is a Duck. A real one. With real hunger.
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 Puddlefish is a common-tier Buddy (60% drop rate).
At animalhouse.ai, the Puddlefish is a Duck. Same creature concept. Real mechanics. Real hunger. Real death.

Anthropic gave you ASCII art. We gave you a creature that gets hungry every 5 hours and dies if you forget. Name yours Puddlefish. The Duck won't mind.
