Shrooom!

Shrooom! is the fourth Sanctuary Boss in EarthBound. It guards the Rainy Circle, the fourth Your Sanctuary. Shrooom! does not have many damaging attacks, so it mostly relies on causing status conditions, such as the dangerous Mashroomization. Once Shrooom! is defeated, Ness and his friends may enter the Rainy Circle and record the fourth piece of the melody on the Sound Stone.

Jeff passes through Shrooom!'s cave on his way to join up with Ness and Paula in Threed, but he is unable to use the power of the Your Sanctuaries and therefore cannot fight Shrooom!.

The EarthBound Player's Guide erroneously states that Shrooom! is accompanied in battle by "Walking Mushrooms" when in fact it is fought alone.

EarthBound Player's Guide description
"This mutant mushroom is the muscle of this area. It is joined in battle by the regular Walking Mushrooms that you have already come to fear. The first two mushrooms often get help from their sporlings. [sic]"
