Grand Son is the step brother of Grand Brother, and the son of Grand Dad and Grandcess Mom. When he says "Grand Flower!" The person he is looking at turns into clones of Grand Dad. He also owns his own Grand Son Clones factory that creates Grand Son Clones. (duh!) Unlike his father, he is not part of the Fleenstones. Unfortunatly, his own brother killed him, he is now Grand Son II.
