The Amarillo Kid is the main antagonist of Mr. Tux. A long time ago, the Amarillo Kid challenged Private to a game of mini golf, back when Private was one of the best mini golf players and was known as Mr. Tux. Private quit after the game, which ended in a tie, because he had to hit a little possum girl's ice cream cone (it was a double scoop ) to tie it up. Though Private admitted that the pressure made him quit after all. He later returns in Showdown on Fairway 18, but this time has a changed personality and requests Private's help. And the end, The Amarillo Kid and Private become friends.
