I've collected a red and a blue starseed and now I don't know what to do . .
First, You are gonna want to put a starseed in the glowing blue orb in the castle thing then wait for it to spawn a little blue ball into the water then you wait for it to become a fish then you take out a starseed by pressing the "I" or the "O" key (I can't remember which one so try both I guess) And then drop it by clicking but make sure you drop it in front of the fish so the fish can eat it and then you just do that with every starseed that the thing in the room asks you for I hope this helps! If not then try to look up a walkthrough
