* The scenario that the humans are shown in the episode "Cat Castle" is one massive case of FridgeHorror. To go into detail, they've been forced into living underground by the Cat King and his fellow cats and do everything they can to avoid laughing because of how much the Cat King hates it, and even then, the cats know exactly where they live and are monitoring them in case they laugh, and while their punishment for it isn't ''too'' bad, it's still extremely nasty, as they throw chili powder firecrackers into the holes which induce extreme irritation to the eyes, which can be upsetting for any particularly squeamish viewers.

* The titular Swamp Hippos that appear in the episode of the same name. On the surface, they are shaped like hippos... but when they start attacking, ''[[BodyHorror their entire body opens up and]] [[MonsterMouth reveals itself as one giant mouth]]''. The words "absolutely freaky" don't even begin to cover it.

'''Twin Masters:''' ''[[PunctuatedForEmphasis Nothing. Left. Alive.]]'' [[WhamLine Your services are no longer required...]]

* [[KnightOfCerebus Twin Masters]]. Although the show is typically lighthearted, Twin Masters mean business and have a genuinely intimidating appearance of a gargantuan, half-blue and half-red, vaguely humanoid entity with a skull sitting on top of its incredibly wide torso and ''twelve hands'' (two big ones and one on each finger), not to mention [[VoiceOfTheLegion their voice is as equally intimidating]] and their motive being plunging Hidden Kingdom into everlasting chaos.

* The leeches in the episode "Leech King" when they're masquerading as the members of Big Green. They have unnaturally green eyes and weird black goo oozing from their eyes, not to mention they also [[RubberMan stretch and bend]] [[BodyHorror in horrific ways]] and [[CreepyMonotone speak in a rather disconcerting manner]]. And in one of the scenes, before the leeches begin replacing [=ApeTrully=] and First Squad, the episode provides us with... [[https://vignette1.wikia.nocookie.net/hero108/images/5/5a/Leech_King_050.png/revision/latest?cb=20150124165750 this]]. [[EyeScream Just try to imagine a couple of big worm-like creatures crawl out of your eye sockets...]]

* In "Pitched Battle of the Air Force Part 2" we get the Twelve Eyed Striped Dumbat, a dangerous fusion of Big Green's enemies created by [[NiceJobBreakingItHero Mighty Ray toying around with Woo's invention]]. First off, this thing is ''[[AttackOfTheFiftyFootWhatever enormous]]'', and very terrifying with its might. The monster takes Jumpy, Sonia and Mighty Ray hostage, who then break free from its grasp and start assaulting the heads, [[HopeSpot seemingly having the upper hand]]. But then, [=HighRoller=] grabs them with Bearstomp's arm and ''[[SwallowedWhole pulls them into his mouth]]''. Not only is [=HighRoller=] ''satisfied'' right after (even commenting on their taste), there's also the fact that two of the victims are ''[[ImAHumanitarian humans]]''. Not helping matters is that [[https://www.davidearl.ca/portfolio/?menu=Storyboards&tab=18&id=26&storyboard=98&image=328&nav=2&thumbs=true the original storyboard]] has [[WhatCouldHaveBeen an unused scene]] that shows what would've been Lin Chung's reaction - ''horror''.

* In the opening scene of "Fox King and the Arachno Tanks" we get to see three fox cubs, but then [[FridgeHorror there's only two of them the next time we get to see them]]. We can only assume [=HighRoller=] actually ''killed the third cub offscreen'', and the fact [=HighRoller=] hung the rest of the family (sans Fox King) in a cage above [[SpikesOfDoom a set of spikes]] doesn't help in the slightest.
* In "Pitched Battle of the Air Force Part 2" we get the Twelve Eyed Striped Dumbat, a dangerous fusion of Big Green's enemies created by [[NiceJobBreakingItHero Mighty Ray toying around with Woo's invention]]. Basically, what happens first is that Mighty Ray, Mystique Sonia and Jumpy Ghostface are kidnapped, who then break free from the Dumbat's grasp and start assaulting the heads. What does it do to dispatch them? It grabs them with Bearstomp's arm and ''[[SwallowedWhole pulls them into HighRoller's mouth]]''. Not only is [=HighRoller=] ''satisfied'' right after (even commenting on their taste), there's also the fact that two of the victims are ''[[ImAHumanitarian humans]]''.
