Summarize:

If Coconut Wheels are already in play on a particular level, some may come frozen under jelly. Free the Coconut Wheel from the jelly before using it. This can be done by making a match or combo adjacent to the jelly. If the Coconut Wheels are free, skip this step. The Coconut Wheel can be activated and used by switching it with a candy next to it. After the switch, the Coconut Wheel will start spinning and roll into the direction of the swapped candy.  If the switch was done horizontally, the Coconut Wheel will roll horizontally. If the switch was done vertically, the Coconut Wheel will roll vertically. The Coconut Wheel will roll over the next three candies in one direction. All of the candies will then become Striped Candies, which will then explode in the same direction, wiping out the columns or rows. If the Coconut Wheel rolled over an ingredient or a blocker, nothing will happen to it. It only works on free candies. With a Coconut Wheel being able to turn the next three candies to Striped Candies, it makes sense to use them for bringing down ingredients, which is just right since it can only be used on Ingredients levels. Just make sure the Coconut Wheel rolls in the right direction to wipe out the needed columns.
Free the Coconut Wheel. Activate a Coconut Wheel. Turn candies to Striped Candies. Purpose a Coconut Wheel.
