When Marvin was trying to explain to the Super Friends about the entrance to King Plasto's headquarters, he told them that he drove his truck through the side of a mountain which opened up like magic. Wonder Woman asks if the driver said "Open sesame" to get it to open. He told her he didn't say anything, it was the tree branch. Wendy asks: "the tree limb said "open sesame?", to which a frustrated Marvin answers "No, no, no!"
