DC x DP Prompt Where it's like Twilight Princess-esque

Midna-esque Danny who needs to get back to the Ghost Zone and get rid of Pariah before he invades the world with an army of the undead. But he's stuck in small almost baby-man esque form or possessing a shadow.

Enter batfamily member (or maybe all of them) who can see him, but have also gotten turned into an animal. Kind of hard to do things in Gotham or wherever they are when you don't have fingers nor can you ask for assistance. But well, invasion by the undead? Banished prince? Who only they can see thanks to being partially dead??? Breakdowns later, stopping the end of the world now.

Time to find a way to the Lazarus pits to try and cleanse the guardians there, which apparently is a thing?? The batfam didn't know that but apparently it's been corrupted for a while- and hopefully they don't slip into like, an in-between state of existence or something. Now if only there weren't several people and ghosts trying to stop them- and they have to avoid the government too?? Some sort of anti-ecto acts?? That's something they'll have to deal with later, after the whole, freeing the lil ghost-prince's siblings and dad and taking down the ghost king...
