History DownerEnding / Supermarioglitchy4sSuperMario64Bloopers

* While more of a NoEnding than a straight DownerEnding, due to the episode not having a resolution, "Clown Fever" ends with the entire Mushroom Kingdom still under the effects of the titular disease, and Mario, the only one immune to it, having to chase down a clown-turned [=SMG4=] (who attributed the mess to not writing the episode properly) to try and stop the chaos himself, and [[SadClown Depresso]] (who inadvertantly started the whole mess) [[SanitySlippage beginning to go mad]] after losing his girlfriend to [=SMG4=].

* "Marioception" ends with Mario suffering many nightmares in a series of DreamWithinADream, with the implication being because he stole the dream invention and [[DisproportionateRetribution E. Gadd's chocolate]].

* "The Final Piece". Zero pretty much wins. He incapacitates all the heroes, making them ForcedToWatch as he begins using Mario and the Guardian Pods to destroy the universe so he can make his new one. The caption promises that things will be “decided” in WOTFI 2021, but how do you come back from an ending like ''that''?

* "[=MAR10=]" ends with [=SMG4=] ([[SanitySlippage having been slowly going insane from working on his "perfect video"]]) forcefully kicking everyone out of the party and angrily lashing out at his friends to leave him alone to his work before returning to his computer. All of his friends are saddened by this, especially Mario, who was going give [=SMG4=] the "[=Mar10=] Day Best Friend Award". [[{{Cliffhanger}} [=SMG4=] then starts livestreaming himself working...]]

* "MARIO BALLIN?!?!" ends with [=SMG4=] losing the match, proving he's not ballin'. However, despite winning, [=SMG3=] ain't ballin' either...because ''Luigi'' is.

* "NINTENDO HAS CLAIMED THIS VIDEO" has [=SMG4=] and Meggy returning with a parody law contract...but the DMCA is turned in first. As a result, all the [=OCs=] fall over with their eyes rolled up, dead. It takes longer for Meggy to go down, dying after giving Mario one last hug, and the only non-Nintendo character left standing is [=SMG4=] standing in the midst of his dead characters.

* "If Mario Was The Last Man On Earth": By the time Mario snaps out of his isolation-induced SanitySlippage, he's inadvertantly ruined the entire Mushroom Kingdom's attempt at a pizza record, causing the enraged inhabitants to jump him the video pauses with ''"To Be Contiuned"'' written on the screen.
