Fill a bowl halfway with cold water. Top the rest with ice cubes.
Melt the dark chocolate.
Add the melted chocolate to a piping utensil or bag.
Pipe scribbles directly on top of the ice bath in a rounded shape to make the monsters. Make sure to pipe a bit closer together around the center.
Top with candy eyes and long rod sprinkles (or flaked almonds) for teeth.
Add a dark chocolate v-shape to the top of the eyes to make the monster look scary.
Remove from the ice bath and allow to dry off on a piece of kitchen roll.
