Yoshi's Island Easter Eggs

Yoshi's Island Easter Eggs is the last secret level in Yoshi's Island DS. It consists of 8 rooms that contain "easter eggs" – an unique condition or conditions that the player must overcome. There are middle rings after each room (which has a locked door and a key to enter it with to move on), so scoring 30 stars is easy for this level, but the challenges push Black Yoshi to the limit. There is also a Stork Stop, but any baby (Baby Mario, Baby Peach, or Baby DK can be used to complete all but one room. The red coins and flowers are spread throughout the rooms. A Message Block delivers what the Easter Egg is at the start of each room:
 * 1) "Grab Lakitu's cloud!" Black Yoshi must hop on the Lakitu that appears, not eat the cloud, to navigate spikes on top and bottom. (2 red coins)
 * 2) Black Yoshi must use Bouncies to hop across a long pit. (3 red coins, 1 flower)
 * 3) "Be careful of the fickle blocks!" A Woozy Guy is enclosed with a switch that activates and deactivates ! Blocks over spikes, at definite time intervals as he jumps up and down. Black Yoshi must time his jumping to get up and reach the door, on ! Blocks as well. (2 red coins, 1 flower)
 * 4) "Let me get on it! Let me get on it!" After using an enhanced Flutter-Jump from a Shy Guy, Black Yoshi must put four more Shy Guys on four separate switches to raise a metal bar to enter the door. (2 red coins)
 * 5) "Be afraid in the dark!" Soon after leaving the middle ring, Black Yoshi is enshrouded in darkness, and must use short-lasting ! Switches that provide light to navigate carefully. (3 red coins, 1 flower)
 * 6) "Use the egg platform to move!" Over more spikes, Black Yoshi must use the egg platform to move under two maces (requiring momentum) without getting stuck without eggs (which is possible). (3 red coins)
 * 7) "Ride the super-fast arrow wheels!" Also lined with spikes, Black Yoshi must time his jumping so that the arrow wheel is facing in a generally straight direction, or it may be too late! (3 red coins, 1 flower)
 * 8) "It's superstar Baby Mario vs. the Piranha Plants!" Only the third time the superstar is seen in the game, and also the only room that requires a certain baby, Baby Mario must kill all the Piranha Plants lining spikes on the floor and ceiling to raise a block to finish the level. (2 red coins, 1 flower)
