Line a baking sheet with wax paper, parchment paper, or a silicone baking mat
Dip pretzels, one at a time, in the bowl of melted chocolate, using a fork to turn the pretzel over . Shake off excess chocolate from the pretzel with the fork and be sure to shake the chocolate out of the bottom hole, so it looks like an open mouth then place onto baking sheet
Immediately press two eyeballs into the top two holes for eyes – add a little extra chocolate if needed to support the eye balls
Repeat with remaining pretzels then allow pretzels to rest and harden (I usually have them set in fridge for an hour!)
