It's a mash-up of Fraggle Rock and The Beatles. I was going for a grainy 60's black-and-white-TV look to it. The idea was "What if the Beatles were from Fraggle Rock?" Therefore, I used reference of specific fraggles from the show to draw these four, but they are not necessarily suposed to be THAT fraggle.
For example I used Boober as Ringo because I thought he looked the most like Ringo. But it's NOT Boober, it's Ringo... as a fraggle.
So, yes, I'm fully aware the Mokey is a girl.
