However, the face is predetermined when you get the egg, so unfortunately you have to restart to a point before you get the egg in question. The only way to choose a certain face is to restart the game and wait for the one you want. So no, it's not a way to ensure that you will have one with a specific face. If you throw the egg, your pet will come out upset. I literally have no proof to back that up, so do with that what you will! I also hear that those hatching from thrown eggs are smaller than the other kinds. I've heard and cannot confirm that a Chao's size changes if you throw the egg. This is by far, the fastest way to hatch it. Release B and use the analog stick to move around, and press B while moving. I think it takes about 10 seconds to get the egg to hatch when you put it down. Rock the egg: You pick up the egg with the B button and, without letting go of the B button, push the analog stick in any direction.Wait: If you're patient, it will hatch on its own.
