[it's not that long a walk, just like a long hallway, except there are no walls and it's a giant tree branch in a giant hippie forest. Once you see the dipped end of it though, it's obvious -- thick, wide, flat, blue mushrooms sprout out along the branch's sides, small and normal at first... and then they increase in size to gargantuan, the biggest easily forty feet across. It's not the "true" end of the branch that Allen stops at, it branches off into many limbs and leaves, but one would have to be pretty adventurous to traipse along further with how high up they are.]
