Jimmy is an insecure child, with a propensity to cry. He is most often seen spending his time with Sarah. Jimmy is highly accident-prone, often seen sporting bandages, casts, and braces (particularly headgear), and is considered the weakest kid in the cul-de-sac. Though Jimmy has a cowardly, delicate, and effeminate personality, he truly wishes to be strong and muscular. He can be crafty when motivated, and had twice made scams that were very successful. Jimmy has shown how deeply attached he is to Sarah when someone tries to take her away from him. For most of the series he wore a retainer to correct his teeth, due to a bowling pin accident during one of Eddy's scams. In one episode, Eddy takes Jimmy under his wing as his protégé. Sometimes the Eds are quick to ruin his dreams.
