Raisant Stomp
In this Challenge Event, you need to stomp as many Raisants, or bugs, as possible to get candy. Simply walking over the black Raisants will be enough to crush them, but you'll have to jump on the larger purple Raisants with significant force. Due to the effort involved, squashing purple Raisants earns more candy. You can even jump on and pound fellow contestants, stunning them for a moment and leaving more Raisants for you. Pounding a fellow contestant will also win you a special achievement.
Super Star Smash
You and your fellow contestants attempt to break open hanging star pinatas. Pressing the A-button swings your bat, while holding and releasing the A-button generates more power. To inflict the most damage, try to hit the star when it's swinging back into you with lots of momentum.
Caramel Apple Gobble
This Challenge Event pits you against your fellow contestants in a caramel apple-eating contest. You have to spin your apple and chomp it clean, making sure not to bite in the same place twice. As soon as you finish one apple, the game throws you a fresh one. You earn points for each quarter apple eaten and for each bite, with bites of the first apple worth one point each and bites of the second apple worth two points each.
Short Fuse!
The Viva Pinata version of Hot Potato, you and your fellow contestants need to toss a Loather, a type of bomb, back and forth until it explodes. You earn one point for each second you hold the Loather, so timing is everything. You need to remain calm, swipe some points and then pass to another contestant just before the Loather blows up.
As the Whirlm Turns
A more difficult variation of Caramel Apple Gobble, As the Whirlm Turns finds you and your fellow contestants in another apple-eating contest, except this time the apples have orange worms called Whirlms. You still have to spin and chomp the apples like before, but biting into a Whirlm will cause you to spit out the rotten piece, toss the apple aside and start on a new one, costing you valuable time.
