Mung is an ogre at Fablehaven. After Newel, Doren, and Seth try to steal treasure from the ogre's territory, their bag full of treasure is dropped by Doren during the escape and they are forced to leave it behind. The duffel bag was left by the ogres as bait until Seth sent his cousin Knox into the ogre's territory. Since Knox was oblivious of the creatures at Fablehaven, Mung ran towards Seth, who had sent Knox to trespass on his territory. Mung continued to chase Seth despite being tripped by the satyrs, and having to jump across a gully. When Seth got to the Sorensons' yard, Hugo intercepted Mung and forced him to yield his right to chase Seth anywhere at Fablehaven. The ogre than returned back to his territory.
