I just watched Philza's Mexican Independance day VOD and came up with this. (Copy and pasted from my YT Comment)
With the knowledge we have as of now (31/12/2023) i believe that this was Rose luring Phil to the birdhouse.
While what she did was a bit cruel, Gods are known to be dicks (Zues as an example), I believe that she trapped him so that he would specifically dream about the HC world, which would make him want his wings back.
And for Cucurucho, i think he was an illusion or magic or whatever Rose used, i believe she used Cucurucho as a way to make Phil distrust the Federation more. Everyone at this point was desperate to get their eggs back and Rose didnt want Phil to be desperate enough to get help from the Feds, so she used an illusion of Cucurucho to trap him as a way to make him hate them.
While Phil before this point expressed sadness about not having his wings, he nerve went out of his way to get them or activley said he wanted them back, but after the Birdhouse hes been trying to get them back, healed, and has let them out from the backpack to have space to relax and heal.
