Shroombear

Description
Takeguma (Shroom Bears) are small rodentish mammals with beady eyes and large noses. They have stocky bodies with short legs and a long thin tail. They have a symbiotic relationship with the parasitic water shrooms that are often found growing off of their backs. When the Takeguma grow weak, the water shroom releases some of the nutrients its been storing so that the animal can keep going.

The water shrooms were a key part in Riko's recovery after being attacked by Tamaugachi. Nanachi planted the shrooms on her wound, forcing a symbiotic relationship the same way they have with Takeguma.

Their danger classification was left unmentioned, though considering they hardly gave Reg and trouble at all it can be estimated at ☆ (Harmless).
