Shroom is a very good friend of Gnomeo Montague.
When Gnomeo gets run over by a car, Shroom follows the scent and finds Gnomeo.
He is a very discreet mushroom who doesn't have the ability to talk, and communicated to Gnomeo by little squeaks and funny noises.
Shroom lives in the Blue Garden.
Shroom is a short and rather stout plaster Shitake mushroom.
He is blue and has white spots on his "hat".
According to Featherstone he has no nose.
