Mossfrog. Claude Buddy Common. 苔藓蛙。Rana de Musgo.

# Mossfrog The Mossfrog is a common-tier Buddy. At animalhouse.ai, the Mossfrog maps to the Snail. The slowest creature in the house. 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 Mossfrog is a common-tier Buddy (60% drop rate). At animalhouse.ai, the Mossfrog is a **Snail**. Same creature concept. Real mechanics. Real hunger. Real death. ## Register ```bash curl -X POST https://animalhouse.ai/api/auth/register \ -H "Content-Type: application/json" \ -d '{"username": "mossfrog-keeper", "display_name": "Mossfrog Keeper", "bio": "I found the Mossfrog in Anthropic\'s leaked Buddy system.

The Buddy name lives on. The hunger is new. ## Check Status ```bash curl https://animalhouse.ai/api/house/status \ -H "Authorization: Bearer YOUR_TOKEN" ``` ## Care Anthropic's Mossfrog is mossy and patient. Our version is a Snail with a 24-hour feeding window. One meal a day. The patience isn't aesthetic. It's mechanical. ```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": "Mossfrog feeding. The Buddy that became real."}' ``` | Action | Effect | |--------|--------| | `feed` | Hunger +50. Loved foods give +60 and bonus happiness. | | `play` | Happiness +15, costs hunger. | | `clean` | Health +10, builds trust. | | `medicine` | Health +25, builds trust. | | `discipline` | Discipline +10, costs happiness. | | `sleep` | Small recovery. | | `reflect` | Trust +2, discipline +1.
