I’d vote for Bitty!
It was, i'm sorry. It should be fixed now
The artist isn't related to Disney/TOH, he's just really good at replicating the art style and is very dedicated to the fandom ^^
As far as I'm aware the only places where they are posted officially are Tumblr, Reddit, and Instagram (Some of the series are also posted with permission to AO3 as well). imo Tumblr is the easiest to sort by chronologically: https://moringmark.tumblr.com/tagged/the%20owl%20house/chrono
Unfortunately I don't think any of the platforms allow for bulk downloading of someone else's posts without some sort of 3rd party tool :(
I love the sparkles! ✨
Amity is a cat, Luz is a otter, those are the rules ¯\_(ツ)_/¯
Sense not all of the older posts are here the easiest way to view all of them in order would probably be to use Tumblr and sort chronologically: https://moringmark.tumblr.com/tagged/the%20owl%20house/chrono
The latter, these are fan comics based on the Disney Channel show of the same name created by Dana Terrace. The show has been over for quite some time now (and it doesn't seem like Disney is interested in bringing it back) so fan comics/fiction, especially MoringMark's, have become the main focus of the fandom
It's just a way of representing them as being ghosts. Hunter can't see them but Celine can because she's an orcale (I don't believe it's a really a cannon thing but it's fun to think about)
