Ok the more I think about this, the more I believe that the protagonist in Poppy Playtime wonāt actually be able to save the surviving orphans, even with help from Poppy. Iām guessing that the orphans are in cryogenic sleep, since Poppy said the Prototype has them in his lab and theyāre all asleep, the thing is though, since Playtime Co. has been experimenting on them for decades, and the only way to put someone in a cryogenic freeze is for them to already be dead.
If we defeat the Prototype, my guess is heās going to activate a failsafe that will take the orphans off life support permanently, effectively killing them as well. All of Playtime Co. will die with him.
I know this is just a work of fiction, but so far the science doesnāt hold up that the orphans are still alive. After all, the Doctor said in his final moments that we saved no one.
