On the episode "Attack of the Mac Snacks," Mac brings in some snacks that Quon Le made using a secret family ingredient. Harry liked them so much that he invested $5000 in them after his first taste, becoming Mac's partner. Harry invites "Mini Mart" Marv to try some, hoping that he will carry them in his national chain of mini marts. Unfortunately, Marv dies after eating them, causing a panic because people immediately suspected the Mac Snacks were poisonous. It turns out that Marv had a heart attack because his arteries were clogged with Marshmallow Prune Gooey.
