The current definition for 100% is "You must collect all the collectibles in every level."

I am not sure what the means and just want to come to an agreement on what 100% is.

What I ¤think¤ it means is getting all medals

It could also mean getting all stars, completing the scavenger hunt, getting in the ball hacks hole / hole of glory, and getting the rainbow (which I still haven't found)
