String Bean is an Urb residing in Urbzville's district, Kicktail Park. It is possible that he is Malcolm Landgraab's son, as on his Urbz profile page, it states on his DISLIKES "gettin' called "Dudley"", which is Landgraab's son. They do have a similar appearance, and Urbz takes place after Bustin' Out, so there is a possibility String Bean is Dudley Landgraab.
