History NightmareFuel / UncleGrandpa

* Everything involving [[NightmareFuelStationAttendant Tony]].

** "New Experiences with Berry Nice and Hot Dog Person" Hot dog person is encouraged to climb a "tree" and ends up being eaten by birds. What does Beary Nice do? Simply smile and call it a "new experience". There is something wrong with that bear!

* In ''Duck Lips'', at the very end, Josie tells Uncle Grandpa the whole duck lip incident has turned her life into a complete nightmare, and, as she does so, her [[NightmareFace face]] suddenly becomes a wrinkled, goblin-like monstrosity with an unnaturally long neck and her voice goes from feminine to a rather raspy, demonic one. What's worse, it [[JumpScare comes up rather suddenly and can catch you off guard]]

* In the episode "Prank wars", when Mr. Gus tells Uncle Grandpa his prank, which involves sending Pizza Steve to a Pizza-eating contest, Uncle Grandpa makes an incredibly [[http://img4.wikia.nocookie.net/__cb20140405150713/uncle-grandpa/images/thumb/5/5e/Uncle_Grandpa_in_Prank_Wars_3.png/500px-Uncle_Grandpa_in_Prank_Wars_3.png disturbing face]] which appears out of nowhere.

* The demon poster seen in "Belly Brothers" (when UG says "I like trains!") can make you do a double take when it's seen.

* In "Grounded", Uncle Grandpa temporarily ''sends Riley to Hell'' (or at least some place filled with fire and monsters where people spend eternity) in order to teach him to not sneak out when he's grounded.

* There's something a bit disturbing about [[spoiler:Aunt Grandma viewing Uncle Grandpa causing her to get ''second place in a science fair'' as grounds to ruin his career.]]

* A ShowWithinAShow Uncle Grandpa likes watching involves these two high school girls giggling after meeting a jock with exaggerated muscles and hair. Their giggling soon turns into insane laughter as their heads melt, leaving only their skulls, and then they turn into demons with ''fanged mouths for torsos.''

* Giant Realistic Flying Tiger's angry expression throughout the "Good Morning News!" segment of the episode ''"Shorts"'' can be pretty disturbing, especially since it appears as if she's looking ''[[TheFourthWallWillNotProtectYou directly at the viewer.]]''

* The [[HellIsThatNoise first time you hear the titular "Mystery Noise"]] in the episode of the same name. A close second would be Pizza Steve's GrossUpCloseUp moments as well.

** Not to mention Krell turning the kid into a grotesque purple monster with a butter knife for a hand. The kid even retains the butter knife hand after being turned back into a human.

* The giant funny face that follows Uncle Grandpa and his friends around is actually very creepy.

** On the other hand, both UG and the kid turn themselves into some serious BodyHorror in the process.

* The whole concept in the episode Halloween special "Afraid of the Dark" is supposed to be Nightmare Fuel in itself. On the other hand, it also has some NightmareRetardant thrown in for good measure to keep it somewhat kid friendly.

* Near the end of "Drivers Test", the psychotic baby that's been chasing the RV the whole episode is revealed to be the driving instructor's son. Cue a very frightening close-up from both of them complete with demonic expressions and razor sharp fangs.

* The manner in which Uncle Grandpa (in truth, "Emperor Krell") gets the boy to stop acting high-and-mighty, which is by having the boy repeatedly make him a sandwich and then breathe fire on it.
