Mini Puft theories

Just some theories. If you haven't seen the new scene for the Ghostbusters Afterlife movie, it's out. Not really a spoiler since these new characters are like the marketable tiny characters of the film, but if you want to avoid them, then spoilers ahead.

There's new characters introduced this week called the Mini Pufts. I have theories about them.

• The first theory I have is that the mini pufts will turn into a giant stay puft. I think it's the most likely to come true, though I don't know for how long they'll stay like that.
• The second theory, which is very unlikely but I think is interesting, is that it's Gozer's poops. This was the case in Ghostbusters Deviations but this will most likely not happen. Why? First off, GBAL is not Deviations, second, that's really gross, third, the mini pufts in Ghostbusters Deviations look little to nothing like the ones in GBAL.
• The third theory is that the marshmallow stuff has essence of Gozer and the Ghostbusters, and that's why they want to rip apart everything, including themselves. I came up with this mostly because of Citizen Ghost, but like the second thing, this might not be the case.
• The last theory I'll put up here for now is that the mini Pufts were summoned by Callie, Trevor, and Phoebe's presence, and probably the presence of Venkman, Stantz, and Zeddemore. I say this because maybe the city Callie moved to was haunted, and spectral energy increased because of their blood relation to Dr. Egon Spengler.

Edit (June 9th): Interestingly, the normal Stay Puft is said to not return in this movie. That's pretty interesting, but it makes sense, since the Mini Pufts would rather kill each other than merge into one. But what is their final goal, if they have one?
