Nyarf

 guns are dart guns used by Wendy Corduroy, Dipper, and Mabel Pines in "Dreamscaperers."

History
They are first seen and used when Wendy and the Pines family are watching Grandpa the Kid. Wendy dully shoots a dart at Dipper but misses, Dipper then reacts in the same fashion. Later, Stan asks Dipper to get rid of a bat in the kitchen, and Dipper is hurt in the process. After Mabel and Soos take care of his injuries, Stan yells at him to unclog to sink, and out of anger, Dipper shoots a dart at his picture. Even later, after Bill Cipher finds the door which, has the safe combination, in one of Stan's memories, Mabel uses the gun to shoot the door out of Bill's hand, and into the Bottomless pit.
