Ep 44. Waterfall Lane

While digging a swimming pool, the gang discovers a piece of tile covered in picture writing and Owl decides that his old friend, Professor Peanut could decipher it, so they're off to the Deepest Jungle by plane, where they search for Number One Waterfall Lane without success. Professor Gobbledy-Gook (Egbert) insists that he can read their picture-writing, but is making it up. They find Prof. Peanut who explains that the tile is his house number, inviting visitors to swim, which the gang happily does.
