I know it’s just a crappy coincidence but part of me still wants to headcanon that Danny grows up to be Chip Skylark somehow.
He can be a ghost-hunting superhero and an astronaut all while dropping the hit single Shiny Teeth and Me. He’s just that amazing
The Phandom has a lot of interesting and awesome headcanons and theories but by far my favorite is that Danny is either related to Chip Skylard (from the Fairly Odd Parents) or somehow becomes him. It’s one I see rarely but I still love it.
