If you look for special sparkling points, you can find mini-games in four areas throughout the game:
During a full moon, go to Beach Cove and tap Tinkerbell so that she glows. Select the orange shining star that appear to start the mini-game.
In Toadstool Hatches, make three triangles on the mushrooms. Select the orange light that appears to start the mini-game. Note: This can also be done at Rose Blossom Chalet.
At Snowfall Grotto, chase the sleeping colored butterfly and pet it to wake it up. Select the orange light that appears to start the mini-game.
Open the flower near where you normally find Rosetta (if you're having trouble, Idalia will teach you how to open flowers).
Find the sparkle on the water, near the Minister of Summer (it must be a full moon, though, or the sparkle won't appear).
Travel to the toadstool hatches and spin above the mushroom on the far right, another skill you can learn from Idalia. Finally, the rainbow butterfly will fly away and leave a sparkle behind, if you wake it during the winter. You can visit Nollie to learn how to wake insects.
