Gross Moose is a Series 5 ST Trashie from The Grubz. He is a chocolate mouse, that looks like the actual animal.
"This Gross Moose is on the loose! Make sure you stay far away otherwise the slime on his antlers might cover you in cack! ...SICK!"
- This is a likely reference to Moose Enterprise's logo.
- His official artwork on official the trash pack website is Fishy Finger's official artwork.
