The security question while signing up for this very forum-
"Q: Who is the green bloke?
Excerpt from the Kickstarter page-
"Our new heroes, Yooka (the green bloke with no pants) and Laylee (the wisecracking lady-bat with the big nose)"
So there you have it. Unless Playtonic changed their minds, both characters have until now been referred to officially by gender, multiple times. I'm indifferent either way, but them's the facts.
