Shrooom!

Shrooom! is the fourth Sanctuary Boss in EarthBound. He guards the Rainy Circle, the fourth Your Sanctuary. Shrooom! does not do much damage, but he has a great chance of Mushroomizing the party. He is, like Trillionage Sprout, very vulnerable to fire, so during the fight, Ness should use PSI Rockin, Paula should use PSI Fire, and Jeff should use bottle rockets, until they become Mushroomized. Shrooom!'s attacks include Lifeup α, to scatter some spores, which Mushroomizes the target, and disrupt your senses, which makes the target unable to use PSI. After defeated, Shrooom! yields 96,323 exp. and $4,086.
