Any College have their service workers, this is the janitor Smokey the Squirrel.
He does his job pretty well, clean the floor, take out the trash "always looking if no micro students are in there by accident" and even remove the poor other micros that get bullied and glued in a chewed gum under the normal size tables.
But sometimes he end up getting one.... or ten of those micro students stuck on his fluffy tail while he do his work.
