i-i draw this too
He starts altering it, and finds out that for ghosts it's like, super easy. He's literally just grabbing bits of ecto and forming it into what he wants, like putty.
He takes inspiration from his favorite Animal Crossing save, and shapes this floating island to be a place for him to just...go chill.
He names it the same thing he named his Animal Crossing island; Potato.
Danny loves Potato Island. It's his new favorite place to go to unwind.
The blob ghosts like his little ecto lakes and ponds, and will take the form of random fish to play in them. Some of them like to pretend to be caught when he goes "fishing", and are very proud when he takes photos with them and tells them what a big catch they are.
There's his house, based on the Animal Crossing one he designed, and there's a few other empty ones as well.
There's shops, based after the ones on his islands, that have no wares and no one to run them.
But that's fine, this is all just so he can relax.
Except one day, a ghost he hasn't met before asks if they can have one of the houses. That in return, they'll run one of the shops.
Danny agrees! He was getting kind of lonely anyways, and he's not on the island all the time.
Then another ghost asked. Then another.
Now his little project island is a bustling avenue of shops and locals, with celebrations for Ghost holidays he's never heard of planned out, and a small city council to gather up concerns and bring them to his attention if the city council can't resolve them.
Usually it's infrastructure, since no one but Danny can make alterations to the island. The political stuff stays firmly in the hands of the elected officials.
Potato Island is a small, peaceful hub of trade and Danny is Very Proud.

Meanwhile, the Justice League Dark is very happy that there's an interdimensional, peaceful trading village in the Infinite Realms that they can do their shopping at with ease.
The locals like to barter, which is ideal for Magic Users, and Potato Island (wild name but whatever) is protected by a very powerful spirit, so JLD members don't have to worry about being attacked while there.
Billy, though; Billy has a whole other reason to seek Potato Island out; he needs a place to live as a human. He can open his own portals and go back to Earth, and he's not stupid, he knows not to eat food from the Realms, but he's...a little tired of being homeless.
As Captain Marvel, everyone thinks he's an adult and that he has a secret base to live in.
But as Billy, who no one in the hero community knows, he's been living on the streets, and he wants security.
So the next time he goes to Potato Island, he explores it, searching for the Island's guardian; Phantom.
He has a favor to ask.
