The Elder Toad is a character Jake mentions at the beginning of the episode "Return to the Nightosphere." The Elder Toad is likely a reference to the Sonoran Desert Toad, whose "juice" cotains 5-MEO-DMT, a powerful hallucinogen, "Mayhaps we drank juice of the Elder Toad," when Finn and Jake wake up in the Nightosphere Jail, disoriented and confused.
