D.W. Thinks Big & Arthur Cleans Up

D.W. Thinks Big: At Aunt Lucy's wedding, Arthur is the ringbearer and their dramatic diva cousin Cora is the flower girl, but D.W. is too little to do anything. However, when the wedding ring gets lost in the pipe organ at the wedding, D.W.'s size helps her.
Arthur Cleans Up: Arthur and Buster are playing frisbee in the park when their frisbee lands in a polluted fountain. Arthur's dad overhears Arthur and Buster talking about the park and Arthur involuntarily becomes the leader of a cleanup crew of kids. Arthur's friends are not pleased with the idea after their parents had been informed and do not help him. But with the help of Francine's dad, Mr. Frensky, and a few volunteers, they manage to clean up the park.
