Get 700 or more points in a world to unlock a bonus challenge panel on the map screen. These bonus challenges are like the ones you get by chance at the end of the stages, but, once unlocked on the map screen, you can play them whenever you wish. Each world has a different bonus challenge to unlock:

• 1 - Flip Cards
• 2 - Scratch and Match
• 3 - Match Cards
• 4 - Roulette
• 5 - Slot Machine

Collect all eight Character Coins in a world to unlock a hard version of one of the minigames. The hard minigame that is unlocked depends on the world:

• 1 - Tulip Shooter
• 2 - Flutter Challenge
• 3 - Bouncy Maze
• 4 - Speed Eating
• 5 - Egg Toss

Unlike the other unlockables, the game won't tell you that you've unlocked these, but they do appear in the Minigames mode available from the main menu.
