Loud, proud and easy to spot in a crowd, Grub Sub fancies himself the life of the party platter, whether there's a party or not!
Grub Sub is a moldy submarine sandwich, with his eyes placed on his top bun. He has slimy lettuce stuck to his mouth, with meat and cheese, and three pieces of tomato at the bottom of his mouth. His top bun is splattered with sauce.
- Grub Sub is similar to Barf Bagette, a Trashie from Series 4 of the Trash Pack.
- In the webseries, he is given the name Meathead, and lacks the yellow eyes. His name is sometimes parsed as Meat Head.
- Despite being Ricardo's best friend, he has the tendency to not be the best towards him, while vise versa can happen as well.
- His figure, static art, and webseries design make him as a nondescript meat sandwich. However, his introduction video makes him a meatball sub.
- The song used in his introduction video is a parody of the Big Mac jingle.
- His static art and webseries design comes in a bread color that none of his figures do.
- According to the webseries, he dislikes kiwi-flavored juice.
- He is the first Grossery to have had an ancestor shown.
- His model in The Grossery Game places his eyes on his front, rather than his top.
- According to Get Well Spewn (Part 2), his granny is a double-decker BLT sandwich.
- According to Lifestyles of The Rich & Famous (Part 2), he was born into wealth, as he knows how to act the classy part. This is supported by the fact his ancestor was wealthy as well.
- Ricardo refers to him as his "footlong friend" as a nickname most of the time.
