Line a baking sheet or plate with parchment paper.
Melt the white chocolate with the coconut oil in the microwave in 30 second increments, stirring between each, until smooth.
Lay the pretzels and blueberries on the parchment paper, using fun cookie cutters to shape them if you like.
Dip or spoon the melted white chocolate over the pretzels and blueberries to cover.
Add festive sprinkles and candy eyes while the chocolate is still wet, if using.
If you used cookie cutters, remove them after a few minutes, before freezing.
Freeze for 20 minutes, until set. Enjoy, and store in the fridge or freezer.
