If Mr. Bigglesworth is on the side of a mountain he just stands there... at an 85 degree angle.... and.... well that's it... It just seems really stupid and the animations are lame for Mr. Bigglesworth...

Oh btw Mr. Bigglesworth is my horse

But srsly take your horse and put it on the side of a mountain at around 85 degree angle and it will just stand there and act normal... So weird... Not a big issue but just looks sloppy and rushed.
