The Dondon was a creature that Han Solo (Peter Griffin) rode in "Something, Something, Something, Dark Side". He rode it while looking for Luke Skywalker (Chris Griffin) after he was attacked by Cookie Monster. It ended up dying due to hypothermia, in which Han cut open its belly to keep Luke warm while he set up the tent. It seems to have been a combination of both a Tauntaun and comedian Don Knotts.
