So, FNF:Jeffy's Infinite Iridia may or may not be canon to SML.
So yeah. The guys behind SML pulled a Twiddlefinger/MaxDesignPro and actually made FNF: Iridia canon to SML. Well, kind of.
For those who somehow don't know what it is, JII was an FNF mod that was made as a successor to the original Endless Aethos mod directed by both BoingBingus/Slingmingo and (formerly) Betasheep. It was meant to showcase the finished versions of cut content from Aethos, but got canned due to constant harrassment from the dev team. Despite that Shucks was made as a One-Shot demo, but a cancelled build exists that has Cordyceps, Revenant and Execretion in it.
The context is that Marvin keeps having nightmares, and most of the characters in these are from Iridia (besides the creepy version of Hoppy that was also seen, who is a bunny character from a cartoon that exists in the SML Universe).
He first sees Chef PeePee (from Revenant) cooking a dismembered Cody in a frying pan, then he seen Poop Warrior Jeffy. Later on, after Brooklyn T. Guy comes over to help Mrvin get back to sleep, we see DETG in the secret room that was in Shucks, which I think is also based off of a previous SML episode called The Secret Door. Both DETG, Marvin and Brooklyn says "Aw Shucks" as well.
Apparently the puppets used were made by a fan, and then mailed to Logan's place. For puppets, these are suprisingly well done. Idk what you guys would think of this, considering Aethos/Iridia is sort of infamous in this community.
Idk if I'm allowed to share is here, but I know that Iridia/Aethos is still kinda popular so uh...sorry, I guess.
