Jimmy is an insecure child with a propensity to cry. He wishes to become famous, and is most often seen spending most of his time with Sarah. Jimmy is accident-prone (usually seen sporting many bandages and band-aids), and is the weakest child in the Cul-de-Sac (as evidenced in "Cry Ed," when his foot broke after a clothes-peg bounced onto it). Though Jimmy has a cowardly and delicate personality, he wishes to be strong and muscular. He can be crafty when motivated, and twice formulated scams that were very successful - even getting back at the Eds with one particularly cunning scheme. Jimmy has shown how deeply attached he is to Sarah when someone tries to take her away from him. Jimmy shows excellent cooking skills in some episodes, using his "Easy-Bake"-style oven to make soufflés and, on one occasion, cookies that were shaped like sailors.
