Break apart the bark and place in Crockpot. Cook on LOW for 1 hour, stirring occasionally.
After bark is melted, stir in pretzel sticks which have been broken in half; stir well to coat with the melted chocolate.
Stir in the crushed peppermint candies.
Use tongs to drop candy mixture into small clumps on wax paper-lined trays, or drop into mini cupcake paper liners.
Allow candy to set until dried; then store in airtight baggies or food containers.
