Some levels have a third, hidden Wonder Seed beyond the ones listed on the map. Many of the Wonder Flower sequences end with a Wonder Seed.
This special flower triggers a trippy reframing of the current level - sometimes the gravity disappears or you enter a twilight realm or multihued bubbles will carry you into the sky. Most levels will have a Wonder Flower to collect. But to find every Wonder Seed will take a bit more exploring. Nearly every level will reward you with one Wonder Seed just for reaching the flagpole at the end.
