A "
little troll"/creepy stalker midget from the much beloved television show, Gravity Falls.
Gideon Gleeful runs (ran, now?) the Tent of Telepathy. A rival business to the Mystery Shack. He was first seen in the episode: 'The Hand that Rocks the Mabel,' in which he continuously guilt tripped her into dates which eventually lead to him almost killing Dipper-
Mabel's twin brother (see Pine Tree.) and himself in the process. His motives seem a bit skewed, as he swears vengeance upon the entire Pines family- but continues to send Mabel love letters and remains persistent in trying to convince her to be his queen. He goes so far as to summon a brain demon in order to exact his revenge, however, this plan backfires. Pretty badly at that.
In the episode Dreamscapers HE CAME IN LIKE A WRECKING BALL.
Heh, but no seriously. He brought a giant wrecking ball to the shack and destroyed part of the sign. It was depressing.
