Jeff and the Gnomes are the main antagonists of the first episode "Tourist Trapped", where they kidnap Mabel in order to force her to become their queen but are foiled when Mabel tricks Jeff into proposing to her and uses a leaf blower to shoot him back at the gnomes causing them to retreat. He appears as a supporting antagonist in "Gideon Rises", where Gideon (using a whistle) orders the gnomes to kick Dipper and Mabel out of Gideon Land, which is the destroyed Mystery Shack.
