Line a cookie sheet with wax paper

Push a treat stick or skewer through four marshmallows. Continue until you have six sticks with four marshmallows each.

Melt white candy according to directions on package, being careful not to overheat. Adding a teaspoon of vegetable oil helps thin the candy if it's too thick.

Pour the melted candy over the marshmallows (do this over the bowl so that you can reuse the excess).

Melt green candy melts in microwave, stirring every 30 seconds and adding vegetable oil if needed. Place in a piping bag.

Repeat step #5 with the yellow candy melts.

Drizzle marshmallows with green candy, then repeat with yellow candy.

Add sprinkles while candy is still warm.

Let marshmallows set on waxed paper, then trim excess candy from the sides with a sharp knife.

Place in an airtight container and store in the refrigerator until ready to serve.
