Role in the film
Shroom is a very good friend of Gnomeo. Shroom might even be considered to a be like a pet to Gnomeo. Shroom does not have the ability to talk, and communicates by little squeaks and funny noises. When Gnomeo is in his statue form, he leans on Shroom. When Gnomeo almost gets run over by a car, Shroom follows the scent and finds Gnomeo.
