Despite Virginia’s confidence, Happy seeks out the help of former coach Chubbs, apologising to his former mentor for his past misdemeanours, as he strives to become good enough to beat McGavin. Under Chubbs’ tutelage, the two head to a miniature golf course so Happy can improve his putting, something he manages with much aplomb. Pleased with his protégé’s advancement, Chubbs gives Happy a present in the form of a hockey stick-style putter. Happy also has a present, the head of the alligator that bit off Chubbs’ hand many years ago. Unfortunately the shock of seeing the beast causes Chubs to fall out of a window and to his untimely death.
Entering the tournament, Happy is determined to win it for his mentor. This is something that Shooter also says that he is doing, mainly to irritate Happy. The first two rounds of the tournament see Happy match Shooter at nearly every hole, much to the amazement and dismay of McGavin. As a result, Shooter calls his crazed number one fan to derail Gilmore’s momentum once again. The following day, Donald runs Happy over in his Volkswagen Beetle before driving into the television tower on the 18th hole. Although injured, Happy refuses to quit the tournament, but he quickly finds out that his long drive, his biggest asset, has deserted him, resulting in him dropping several shots ahead of the final few holes.
Thankfully, Happy applies a lesson he learnt from Chubbs, managing to find his happy place, whilst an important morale boost from his Grandma helps him regain his focus. From here he goes on the warpath, storming back up the leaderboard, much to the chagrin of Shooter, who as a result loses his own focus and ends up dropping shots. By the 18th hole the two are tied up. Shooter then goes on to hole out for par. Unfortunately as Happy lines up his putt for birdie, the previously damaged television tower collapses under the weight of numerous fans, falling onto the green and blocking Gilmore’s path to hole. Despite calls from Virginia to suspend play until the mess is cleared up, Shooter argues, stating that he had to hit a ball off a fan’s foot earlier in the tournament. Virginia then implores Happy to hit it around the tower and putt in for par, which would take the game to sudden death. Gilmore thinks otherwise, using his training at the miniature golf course from earlier on, he hits one seemingly crazy slap shot against the windscreen of the stationary VW, the ball then rebounds onto the television tower where it rolls down the piping and on to the green and into the hole, winning Happy both the Tour Championship and his Grandma’s house.
Shooter, who has not been noted as a decent loser, hysterically robs Happy’s gold jacket but gets quickly hunted down by a Happy-friendly mob. The movie finally ends back at Grandma’s house where Happy is being congratulated by Chubbs, Abraham Lincoln, and that alligator!
