Ella and Felix have to solve a gigantic, smelly problem. The mellephants, a mix between elephants and fart pads, create big trouble in the jelly green Twirlytown. The mellephants fart. They are not regular farts either, they are noisy, stinky farts which make everyone else float away, high up in to the sky.

Can the Explorers’ Club find a solution, without drowning in green jelly?
