| Defeat The Lamb for the 1st timeThe gate is open!|
Mushrooms appear as early as The Caves and also can replace Hosts. Mushroom is unlocked by defeating The Lamb for the first time.
Mushrooms start out by hiding inside of their cap. While inside, they take only 25% damage. Occasionally, they pop out for a few seconds, shooting red shots in either the cardinal or diagonal directions.
- Unlike Hosts, Mushrooms deal contact damage.
- Mushrooms will not resist damage while petrified.
- If Mushrooms aren't unlocked yet, they are replaced by Hosts.
