Anemaniac (or maybe Oddly Oddity, whichever works best) but Secret History Tails and Molly/Iamemeye.
If you couldn't tell given the title, they're based on Ollie from "BATIM 2017 prototype" and "Out of the Ink Machine", the premise is generally the same where it pokes fun at THOSE fans that think they're better than the creators when there's nothing necessarily wrong with the source material, it lulls the "fan" into a false sense of security with a fake remake/retake called "The Return of Insanitails aka There's Something About but good" and after a bit, it slowly reveals itself to be not what it seems.
Molly has a false form(not shown here but I'll show it at some point) that resembles the actual Secret History Tails but it's very slightly off and voice wise, it's either just sentence mixing random audio or simply a kinda bad impression of the crazy fox. Molly also has a fat form(remember the OG vid for context).
Molly can be rather mischievous but is otherwise harmless, they also partake in activities that any child would like playing and drawing, they're also fine with other versions of the fox.
They are pretty much genderless and goes by any pronouns and that includes neos since it doesn't mind, they're also genderfluid.
Their other name(their real name), Iamemeye is pronounced like "I am, am I".
(The second image is not a joke, Molly/Iamemeye IS canonically a baby, they're only three years old.)
Hm, I wonder how the Mashed community is doing? Maybe I'll see some cool art or stuff...
(Casually checks Twitter via the Twitter reupload site I use.)
"Erm, I believe Mashed fell off..."
"Mashed's videos suck now..."
"They ruined Secret History Tails..."
"Erm, slop much?"
"They're milking it dry!"
(Blah, blah, more complaints, blah, blah, no understanding, blah, blah.)
Me:
(Rant below.)
I'm legit sick of these complaints with not just Secret History Tails' characterization but also with Mashed in general!
If you think the vid looks dumb or whatever, don't watch it, you can easily just skip it, they're not forcing you to watch it.
I've dealt with witnessing this crap for nearly 3 years, ever since TSAA part 3 came out! If it weren't for that series AND Friday Night Funkin' in a way, you folks would still be asking when Secret History Tails will return.
Also, I'll just leave this tweet by Pastra here.↓
If you wanna know what slop is, try fucking AI channels, content farms or channels that plagiarise other people's vids, those are slop, not some fucking channel that just makes parody vids with the odd music video that are made by humans who take their sweet time when making these things!
It's ok if you don't like something, just don't call it slop or hate on folks that like it just because you don't like it.
