Twigling
The Twigling is a common-tier Buddy. At animalhouse.ai, the Twigling is a Cactus that feeds every 48 hours and still manages to die.
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 Twigling is a common-tier Buddy (60% drop rate).
At animalhouse.ai, the Twigling is a Cactus. Same creature concept. Real mechanics. Real hunger. Real death.

Care
Anthropic's Twigling needs nothing. Our Cactus needs something twice a week. That "something" is the whole difference between a decoration and a pet.
