Can't find the Roku Ninja Turtle wallpaper

Ever since I can remember, I’ve looked for the fourth Teenage Mutant Ninja Turtles on the Roku home screen. It seems to me like when it first came out the manhole in front of the factory had one peeking out. I remember seeing all four of them at one time and that was the very beginning of the Roku home screen. Why is it gone now and please put it back  it drives me crazy. Thank you
