What would that be implying? That this character just threw it? Because as is, this character is representing either Dennis or Charlie after Cricket blew sand at them. But Frank the Trashman never got hit by sand at all.

EDIT: I am happy to make a version with a trash can for you, I just need to understand what you have in mind. If you were to make even a sloppy doodle of where you imagine the trash can in this photo, that would be immensely helpful for me.
