I am told that Argo started as a stallion, later was referred to as a mare, and still later, after all the main human characters existed in a state of suspended animation for twenty-odd years, dropped a filly which grew up identical to her mother and also went by the name Argo (so as, one assumes, to preserve the illusion of continuity for the television audience).

Answer: Samson
This large white horse with black mane and tail never speaks (unlike many Disney animal characters); however, he certainly has a personality. He's smart enough to find his way home, and he seems somewhat aggravated when Phillip wants to deviate off course to investigate Aurora's singing. Phillip is able to entice him with the promise of carrots. However, when Samson causes Phillip to fall into a pool of water, Phillip indignantly proclaims: "No carrots!" Later, Samson is invaluable to Phillip in his escape from Maleficent's castle and in his rescue of Aurora.
