Gnomes

Gnomes appear in the episode "Tourist Trapped", where they capture Mabel Pines to try to make her their queen. Dipper saves his sister from them. The book, 3, classifies them as "little men of the Gravity Falls Forest." Manotaurs say they live in trees. There were no known weaknesses until Dipper and Mabel blew the gnomes away with a leaf blower. The gnomes were first disguised as "Norman," whom Dipper believed was a zombie. Mabel has a crush on them because she thought that "Norman" was a vampire. Their leader is Jeff. In the book 3, their creature number is 24. They can turn into a giant gnome monster by stacking and climbing on top of eachother.
