Trish was Wheeler's girlfriend before he joined the Planeteers. He sees her again in the episode Talkin' Trash, and discovers she is part of a gang vandalising the neighbourhood. She is known as "Trash", due to her ability to 'trash' the neighbourhood, mostly with graffiti.
Trish successfully mugs Wheeler at the start of the episode, and steals his Plaeteer ring. He manages to steal it back, before trying to convince her to drop her criminal behaviour and take more pride in the place she lives.
Wheeler saves Trish's life after she sabotages Verminous Skumm's helicopter and falls into the river. He pulls her out and they share a kiss.
It is unclear whether or not the other Planeteers are aware of Wheeler's relationship with Trish.

Trish is voiced by Kath Soucie, the same voice artist who provides the voice for Linka.
