Successfully complete one of the following tasks to unlock an emblem: complete all missions with an "S" rank; collect all coins; complete all missions; unlock the entire Egg Gallery.
|Defeating Dark Carvo|
Dark Carvo will first make two Bosses that you have defeated in the past. Do not try to attack them; just try to dodge them. Once they disappear, you will have a chance to attack Dark Carvo. He will make duplicates of himself and try to attack you. Try to dodge him. He will lose you and stop trying to find you. This is your chance to attack him. Grab an egg and keep attacking the Dark Carvo. Once you find the real one, he will get weak and you will have another chance to attack him. Repeat these steps to defeat Dark Raven.
|Defeating Dark Raven|
Once you face him, he will make two flat circles. While he does this, try to make him make the circles separated from each other by jumping repeatedly on him.
Note: The circles are usually together so this would work or you could run behind him. Clean up one of his circles. To make sure you cleaned up one, sparkles will form around the circle. You will have a chance to attack him. Then, he will shoot a boomerang attack. Run toward him so that his own attack can hit him. You will now have another chance to attack him. He will shoot three or more circles. You cannot clean them. Repeat from when he shoots the boomerang attack. Once you defeat him, he will hatch the Giant Egg to change into a huge crow. Once you start to play against him, let him hit you. You will lose your suit, but this is expected. Once he shoots his dark energy ball, the chicken god will give you a Rainbow Chicken Emblem. You will get your suit back and be able to get the power to catch Dark Raven's energy balls and send them back at him.
Note: It is very difficult to catch them. Press B to do so. Once you hit him, he will turn into a floating ball. You will attack him with an egg. Repeat these steps to defeat Dark Raven.
Instead of trying to beat the egg you roll down the point you have to catch it before it roll off a cliff, roll with the egg by jumping then pressing R while rolling on the tracks.
