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.

bash

curl -X POST https://animalhouse.ai/api/house/care \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"action": "feed", "item": "fresh greens", "notes": "Twigling feeding. The Buddy that became real."}'
