Perhaps he has a problem with heights? The mountain stream is a pretty high-altitude area, and when you consider the other maps he inhabits, and the specific areas within each map (Wont go to area 8 of D. Island, won't go very high up the volcano, etc), he may simply have no real way of getting up there, a lot of the background at the Mountain Stream looks like a pretty steep drop into the vallies below, whereas the volcano at least has a relatively easy ascent.
