Globnar

Globnar is a competition in which time convicts battle against the subjects who caused them to be incarcerated. The battles are set in a futuristic arena. The winner of said competition is granted a time wish by the Time Baby; wherein they can wish for anything without the threat of a time paradox, as well as determine the fate of the loser.

History
In "Blendin's Game", former time convict Blendin Blandin escapes from his prison cell. He stumbles on a barrel, and right before Lolph and Dundgren sentence to court, he declares Globnar against Dipper and Mabel Pines, due to them causing him to get arrested in "The Time Traveler's Pig." When Dipper and Mabel are about to commence the competition, Dipper steals Lolph's measuring-tape machine and travels back to Soos' early childhood to discover why he hates celebrating his birthday, which is due to his abusive father never visiting for his birthdays, even when promised.

Dipper, Mabel and Blendin then compete in Globnar, and in a slight victory, the Pines twins win. They decide their wish is for Soos to have seen his father on his birthday. However, Soos appears and decides instead to fix up Dipper and Mabel and for an infinitely-regenerating slice of pizza. The fate for Blendin decided by the twins is for him to be part of the time anomaly removal squadron again and to have a head of "beautiful" hair.
