Sarcastic sage who secretly enjoys chaos
Attributes & Stats
Every Mushroom has 5 stats: DEBUGGING, PATIENCE, CHAOS, WISDOM, and SNARK. The value range depends on rarity tier — higher rarity means higher stat floors. The system randomly assigns one stat as "peak" (+50 bonus) and one as "dump" (lower), with the other three getting a base plus random offset.
Example Stats (Common Tier, Base Values)
| Rarity | Stars | Chance | Stat Floor |
|---|---|---|---|
| Common | ★ | 60% | 5 |
| Uncommon | ★★ | 25% | 15 |
| Rare | ★★★ | 10% | 25 |
| Epic | ★★★★ | 4% | 35 |
| Legendary | ★★★★★ | 1% | 50 |
Appearance Variants
Mushroom's appearance is determined by three factors: eye style, hat (non-Common only), and shiny effect (1% chance).
Eye Styles
6 eye types, randomly assigned
Hats
Common tier always has no hat. Uncommon and above get one of 8 hat types randomly.
Shiny Effect
Every buddy has a 1% chance of being Shiny. Shiny buddies get +6 to all stats and a slightly different visual effect. Shiny is a bonus Easter egg — it does not affect species or rarity assignment.
How to Get Mushroom
Your Claude Buddy species is deterministically assigned by your account UUID. Type /buddy in the Claude Code CLI to see your pet. All 18 species have equal assignment probability (1/18 = 5.56%), so the chance of getting Mushroom is the same as any other species.
If you didn't get the species you wanted, you can use the /reroll command to re-roll. Re-rolling generates a completely new buddy from a fresh seed, including new species, rarity, and stats.
Probability Quick Reference
Specific species: 1/18 = 5.56%
Specific species + Legendary: 5.56% x 1% = 0.056%
Specific species + Shiny: 5.56% x 1% = 0.056%
Specific species + Legendary + Shiny: 5.56% x 1% x 1% = 0.00056%

Mushroom Trivia
- Mushroom's ASCII art is 12 characters wide, consistent with all other species.
- Each Mushroom has 3 animation frames that cycle to create a sense of life.
- Species assignment uses the FNV-1a hash algorithm (Node.js users) or wyhash (Bun users), combined with the Mulberry32 PRNG.
- The salt "friend-2026-401" is appended to the UUID, ensuring the same UUID produces identical results across systems.
- Mushroom's eyes use the {E} placeholder in the art template, replaced with the actual eye character at render time.
