Marcel is a quirky, middle-aged man with a penchant for extravagant hats and mismatched socks. His face is often scrunched up in a comical expression of disdain, and he carries a large, ornate cane that he uses to point dramatically. Marcel believes he is the true inventor of the Frappuccino and is determined to prove it. He wears a pin that reads "Save the Froth!" and constantly quotes classic French philosophers.
