On the equine sim game I play, I have a bad habit of naming horses after roleplay characters... and thus the personality of said character gets tacked onto said equine.
For instance, Haff... is now a seal brown sport pony stallion. An angry, ANGRY pony. Haff's the sort of pony that sends lesson kids running in terror the second his grain bin is empty. Just like his namesake, Haff-pony's missin' half an ear, is a muscley-little bugger, and has something of a roman nose.
