I believe that they're two multiverses like ultra-strong is red bears and cleaning people's butts, while in ultra-soft is the same except everyone uses this as pillows, have blue bears, and having too many making it less (sometimes they don't) so this is so they're two separate universes with almost the same thing happening to them in this episode.
Bears poop heavy and plentifully so that's why you see bears in a toilet paper commercial and on baby diaper stations in restaurant bathrooms. Bears really go when they go and they go about 60-70 times a day I read in a book about wild bears! Wowee! Let's hear for the bears! They eat alot and they poop alot!
1 red bear to another: "Hey, ever wonder why we're here" The other red bear: "It's one of life's great mysteries isn't it? Why are we here? I mean, are we the product of some cosmic coincidence, or is there really a God watching everything? You know, with a plan for us and stuff. I don't know, man, but it keeps me up at night." 1 red bear to another: "...What?! I mean why are we out here, with this toilet paper?" The other red bear: "Oh. Uh... yeah."
