Cookie Monster faces his toughest challenge yet in “Star S’Mores,” a “Star Wars” parody brought to you by the letter S, for “Sesame Street.” In “Star S’Mores,” Cookie Monster plays Flan Solo, who together with the venerable Jedi Luke Piewalker and Solo’s trusty companion Chewie the Cookie, is tasked with saving Princess Parfaita, who was kidnapped and held prisoner on the Death Star. Not only must Flan Solo and friends fight the evil Galactic Empire, Solo must also battle his own desire to devour his chocolate chip cookie pal Chewie. “Star S’Mores” is a good, cute way to teach kids about self-control, and is a pretty fun short for adults as well.
