The main purpose of this suit was to keep Jimmy safe and prevent Eddy from trying to compete to get everyone else's attention by injuring himself (he faked an injury from a Swedish meatball and later went on a runaway frying pan motorcycle style until he crashed into a dumpster). Edd created the suit by placing a rubber glove around Jimmy and having Ed inflate the glove and tie it in a knot in the style of a balloon. When Eddy had everyone in the palm of his hand, Ed arrived with Jimmy in his bubble suit. Sarah panicked and try to save Jimmy thinking he will get hurt until Jimmy assures her that he will be fine since Edd made him safe. Soon all the kids (and Ed) are having fun with Jimmy with no concern to his safety since he is now protected within the suit. Edd believed that will stop Ed
