Sonic has been causing troubles for Doctor Ivo Eggman for many years. Since the Doctor has the habit of spoiling everything while getting the Chaos Emeralds, it’s no real surprise that Sonic the Hedgehog fans will try to stop him. By wearing the Sonic the Hedgehog costume, the adults as well as kids will take on the video game persona. They can ensure that Doctor Ivo has a bad day by collecting rings and freeing the animal brethrens. The costume features blue long sleeved shirt with a foamy layer at the stomach, two blue spikes on its back, white foam gloves, and red/yellow/white shoe covers.
