Ted is a museum tour guide who gives weekly presentations to schoolteacher Maggie Dunlop and her students. The museum's owner, Mr. Bloomsberry, informs Ted that the museum is losing money and will have to close, to the delight of his son Junior, who wants to replace the museum with a commercial parking lot. Ted impulsively volunteers to retrieve an ancient forty-foot tall African idol, hoping that it will attract visitors. He is outfitted with a bright yellow suit and hat and boards a cargo ship to the African jungle, where he discovers the idol to be only three inches tall. He sends a photograph to the museum, but the image's angle leads Mr. Bloomsberry to believe that the idol was even larger than he thought. Meanwhile, Ted gives his yellow hat to a happy and mischievous orphaned monkey living in the jungle. Not wanting to be left alone, the monkey secretly follows him onto the cargo ship. Back home, Ted finds advertisements for the idol all over the city.
