The Marshmallow Forest is a location on top of Mount Zubba Bubba.
Appearances[]
The forest first appears in Perfecto Party, when Walden drives up there to collect some marshmallows for Wubbzy's Marshmallow Lasagna.
It then appears in The Wuzzleburg Express, where it serves as the last stop for the Wuzzleburg Express. Wubbzy and his friends almost crash the malfunctioning train there, but luckily, it stopped before it could do any damage.
