I only have one:

Lumpy used to be much smarter when he was younger, and his antlers were normal. He also had qualifications for almost every job possible. One day  (set roughly fifteen years before the HTF resurrection cycle) he went on a trip with a fellow moose, and the duo got stranded in the desert. Lumpy saw his antlers get destroyed by a tornado (same way as Just Desert). Eventually his friend died of extreme thirst on the trip, and Lumpy, who was also much crueler at the time, decided to take his antlers for his own, but upon shoving them in his brain they got stuck and now change directions. This gave him severe brain damage which made him dumber and kinder. However, his old self shows up occasionally.
