I completed the map quests and have 86 starites. Where are the rest?

I've completed every quest in every area, and the world map is chock-full of check marks, but I only have 86 starite out of a possible 106. Where are the rest of the starites?

Escape (Menu) -> Shards -> Object shards

These are pretty much hidden achievements such as the PBJ one:

(wear maraccas and a banana suit at the same time to get a shard.)
