Surprise!! lives up to its name by catching unsuspecting Yoshis off guard with volumes of secrets and unexpected enemies, such as Shy Guys lurking in trees and detours through the clouds
At the very beginning of the level, you'll find a Fuzzy Wiggler, that when jumped on all segments, will give you a melon. Directly in the ground below the Wiggler is a bunch of coins. Just sniff to find the right place. A bit farther ahead, get as many eggs as possible from the Egg Block. Dodge the spider and keep going. Just beyond there are two signs with a melon underground in-between them. BEWARE! Once you slam the ground, a lot of Shyguys will pop out of the tree along with the melon. Past that is a Question Bubble that, when shot, will make a path of clouds into the sky. At the top is a Special Heart. Ahead, you'll find a couple of more Fuzzy Wigglers, the #1 Miss Warp, and an underground melon directly next to Miss Warp.
Keep going, and eventually you'll run into two Blue Rock Blocks that guard a Question Bubble. Break the blocks and shoot the bubble to reveal a vase. Inside the vase in a Balancing Act mini game, but before you start, run ahead and kill off any Shyguys that could be in your way. After doing that, begin, and the path should be completely clear of any obstacles. After completing the mini game, head into the end vase and continue on.
Outside of the vase, slam on the yellow pipe that will be directly in front of you to make a Special Heart (and a lot of Shyguys) appear out of thin air. Continue heading on, dodging Flyguys and Spiders on the way, and you will soon reach Miss Warp #2, and behind her, the next area.
This next area has a type of enemy that only appears in this level: the Air Bag. The very first Mystery Crate will harvest one, so just shoot the box to make him pop out. To defeat him, just shoot him on the "X" patch on its chest. You will receive a melon for defeating him, along with every other Air Bag. Keep heading forward and you will reach a Question Bubble that has an Inflatable Friend inside. Just stand on the platform on his head and move the control stick the direction you want him to go. In the sky is the third and final Special Heart. From there, just keep heading onward to Miss Warp #3. Past her is a group of floating platforms and a Mystery Crate harvesting a White Shyguy. Keep going onward and you will reach a Bird Thing in trousers that has a bunch of baby bird things following. You can collect the baby birds and use then as boomerang ammo! They're really good to use because they always come back after throwing them. Just a bit farther on is Miss Warp #4 and the end of the level.
