Image of Jonny 2x4

Jonny is a kid in the Cul-de-Sac who is quite often a nuisance to the other kids. Jonny has a huge, bald head, which is often the butt of many jokes and repeatedly gets caught in branches whenever he climbs trees. He talks a lot and frequently gets on the other kids' nerves. He is rarely seen without his imaginary friend, a board with drawn-on eyes and mouth named Plank.

Jonny seems kind, innocent and gullible, and he often forgives people no matter what they do. He does not seem to mind the antics of the Eds, as he befriends them and sometimes even enjoys spending time with them.

He probably gets his nickname "Jonny 2x4" from his imaginary friend Plank, who happens to be a 2x4 piece of wood. He has one of The Cul-de-Sac's darker skin tones alongside Rolf, and is usually seen in a white T-shirt, jeans, and sandals.
