Using Starite Vision.
Starite Vision is an important feature only in Scribblenauts Unlimited. When you use the Starite icon in the top corner, the screen will turn blue. The objects that give you Starites/Starite Shard you haven't collected yet turn yellow/orange and has a star pattern over them. The sound when it's in use is the NI Massive patch, called "Ascending" on the C note.
