These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Crowning Moment of Heartwarming: The last part of Skellington's Revenge has Mobros himself thanking his viewers for supporting him throughout the years and that he was glad to be back on YouTube.
There's something adorable about Fluttershy hiding behind RED Scout when she's scared.
Misaimed Fandom: His "Top 20 Worst SpongeBob Episodes" videos attracted subscribers who thought his account was a rant channel, one of the reasons he removed them.
Moral Event Horizon: The Black Hiver crossed this when he killed and corrupted Fluttershy, and later killed Edd and Eddy. While he had a motive for killing the RED Team (they tried to fight and defeat him), the Eds and Fluttershy were no threat to him, meaning that he killed them simply because he wanted to.
The Black Hiver in "Skellington's Revenge", a demonic version of Bugs Bunny. With the voice of the Dollmaker.
The climax of "Skellington's Revenge" which sees the deaths of almost everyone in the group; RED Scout and RED Soldier are caught by Black Hiver's evil glare and have their souls ripped out, followed by them being turned into robots, Patrick crashes into the ground and is eaten by the now homicidal Patchey the pirate, Fluttershy is transformed into a monster with chainsaws for arms, Eddy, Double D and RED Spy are burned alive as well, and RED Medic is torn apart by the robot versions of his former teammates.
