He is a emerald green school backpack shaped like a rounded rectangle. A zipper runs along his body and he has two adjustable shoulder straps on his back with a darker handle sticking up from the top of him. There is also a round front pocket on the lower half of his front, which causes him to have his face placed rather high on his person compared to other objects. His arms start where the zipper leaves a roughly square space on each of his sides. canonically accurate liam yay!!
