|Debut||The Big Weigh In|
An enormous flightless bird that appeared in The Big Weigh In, and that Lumpus wanted to eat to gain weight. Described by Lazlo as being "97% fat" and "the goat of the bird world", the Lardadoodle can and will eat anything it can reach, including nearly all of the contents of Lumpus' kitchen, various belongings of the campers', and even Lumpus and Lazlo. It can also lay enormous eggs containing things it has eaten. In the end, Lumpus realizes the error of his ways and promises never to attempt to eat it again, which the motherly bird reciprocated by feeding Lumpus forcefully with worms.
