Mr. Greenhooves

Hayseed is a background pony designed by series art director Ridd Sorensen.

Development
Hayseed has one of the more distictive designs among the various characters. His name is not spoken on-screen, but Sorensen names him "Hayseed" in a post on deviantart. He is usually seen holding a stalk of wheatgrass in his mouth, which was originally intended to be a corncob pipe that produces popcorn, with Spike eating the popcorn as a gag for the show; the pipe was nixed by Standards and Practices. His hat is a nod to Craig McCracken's Wander Over Yonder.

Appearances
He first appears in Boast Busters, pulling a wagon filled with bales of hay. He can be seen with his wagon in tow on two other occasions: briefly in an establishing shot in Bridle Gossip; and in Feeling Pinkie Keen, splashing mud on Twilight Sparkle as he trots past.

In The Best Night Ever, Fluttershy follows what she believes to be bird song, only to find out it's Hayseed whistlig while he tends to the gated gardens of Canterlot. Both the whistling tune and the line "whistle while I work" are references to Disney's Snow White. He later sets off the trap Fluttershy constructed to catch some animals.

He will reappear in season two.
