Melt green candy melts and white chocolate wafers. Pour the white onto a smaller baking sheet lined with parchment paper.
Add green candy melts into different places and swirl with a knife. Smooth out carefully with a spatula.
Quickly before the candy melts and chocolate dries add the green sprinkles, airheads rainbows (cut), gold sanding sugar, and four leaf clovers marshmallows.
Let the bark dry then break into sections for serving. Store in a bag in the fridge.
