Cover your dowel rod in Duck Tape®.
For the handle, cover the bottom of the dowel rod in Duck Tape®.
For the fishing line, cut a 54 in. long piece of yarn and tape the end of it right next to the handle, then again in the middle of the rod, and then at the end of the rod.
Tie a metal washer to the end of the fishing line.
Draw shapes for your sea creatures on the back of a Duck Prism® Sheet. You will need 2 identical shapes for each of your creatures.
Cut out your shapes.
Remove the backing of each shape and place a magnet in the middle of each creature so it's sandwiched in between the 2 pieces.
Repeat steps 5-7 to create other sea creatures.
