As, again, requested by Rich ($$_Rich_$$), I am doing a Mushroom Gorge Gap Jump guide.
First of all, your combination. The best combination for this shortcut is Funky Kong+Flame Runner because it has enough speed to carry you across the gap and enough weight to not let you...
This is a guide that will teach you how to do the Rainbow Road Moon-Jump correctly. Some people have trouble with it, so I felt like it would be good to help out.
So, what most people forget to do is pick the right combination. There has been a lot of debate...
