Attitude Plenty is the second child and only son of Bob Oscar "B.O." Plenty and Gravel Gertie. His face has not been shown, but he is apparently quite gruesome, with dark, wiry hair like his father.
Attitude Plenty was named after Eddie Tude, a pizza delivery driver who took Gertie to the hospital when she went into labor. He has a tendency to throw objects at his father's head with alarming accuracy.
