Charlie’s Horseshoe Crab costume - 2018 Halloween Costume Contest - Kimberly, the 'Horseshoe Crab' costume creator writes: Charlie, 4 years old, loves ocean animals and decided she wanted to be a horseshoe crab for Halloween. Her Dad made the costume using EVA foam exercise mats (using a heat gun to mold/sculpt the right shape), contact cement, and a Plasti-dip base coast with a spray paint finish. Spandex was used for the joints between the segments, so she can get around pretty well. The costume is put on using a handmade vest with Velcro straps for easy on and off.
