I got there too. It is somewhat difficult because you have to use several jumping techniques in a row. Honestly, I also expected something else besides the Easter egg.
Me myself I love that there's acknowledgement at least! Most players wouldn't bother going all the way over there after they already found the heart piece and gold on the easy sections, so all I needed was a little "Hey you did it!" to be happy, a little pat on the head for going above and beyond with my dedication for exploring random shiz.......
More to the point, it wasn't a literal statue of some hand flipping me the bird.... Still mad at you for that Dingaling, and nothing else of those games.
