Lewis does the Peter griffin dead pose, gelatin tells PSB to not tell announcer about his elimination for the timeline, Dreartop is on one of the posters they made for ice cream advertisements, as well as Cary’s little stick figure guy, Fries and Gelatin eat themselves during elimination because both are canonically cannibals, speaking of fries, gelatin eats one of fries’ fries, which is part of the reason how he lost some of his Fries in IDFB. A bag of barf is on the prize wheel, which is obviously referencing Barf Bag. Handstand contest was on the contest wheel which is a reference to one of BFDI’s contests, as well as Run to that rock over there and back which is a possible SpongeBob reference. Speaking of SpongeBob references, Pencil says "I can’t hear you" which is potentially another one. Go mining for yoylelite is potentially a reference to Minecraft as well (on the contest wheel still).
In the Bfdi acronym segment, Coiny and Nickel have a distorted effect between them, which is a reference to how they can’t be next to each other without making a money portal from 2 separate parts of BFDIA 5
the scene where coiny and ruby were mixing the ice cream and they say "mix,mix,mix,mix,mix!" that can be a reference to golfball doing her cake in bfdi 4
Thing u missed: in bfdia 9, in the needle and bomby scene, they do specific actions to create the bfdi acronym. Also pineapple is voiced by websforevs (i think?)
