I know literally nothing about Walkabout, except that he’s a mutant kangaroo from the 1991 wave of TMNT figures.
I got one, and painted him up to better match the way I paint TMNT toys.
I have very little to say about this guy, but that actually made him a little more fun to work on — With no preconceived expectations about who the character is, I was able to just sorta do whatever I wanted. And that was freeing.
I presume Walkabout, along with the rest of the Teenage Mutant Ninja Turtles franchise, is owned by Nickelodeon.
