In the first episode of Legend of Spider-Boy, Peter Parker is framed for a prank by Flint, who has been bullying him for years. Later on, Flint tries to fight Peter, but Peter all of the sudden overpowers him and beats him. The next day, Flint shows up to first period (Mrs. Osborn's class) early for a change. He notice Ms. Osborn isn't in the classroom, and he looks at the contents of her desk. He notices a weird plastic bin with a sheet over the top. Flint opens the bin and there is green, glowing sand inside. Flint grabs some, and puts it in his pocket.
