You will need:
2 different sized circle hole punches
scraps of paper
Punch 2 circles with the largest circle punch. Take a “bite” out of the top circle with the smaller hole punch.
To make the fins and tail punch 3 of the smaller circles. Fold them in half and cut out a heart shape. Glue to the large circle that will go in the back, then glue the circle with the bite on top.
