Ellis is now best friends with a grumpy, talking popcorn kernel. Yes, REALLY! Together, they're secretly handing out popcorn to Ellis's classmates (since her school is now officially a "Healthy School"—blech), and everything is great. Bob is even learning how to control his hanger. (Kind of.) But Ellis and Bob are in danger—visitors from the possibly nefarious Popcorn Co. are following them, and it's clear they're after Bob! Will Ellis be able to keep Bob out of their clutches?
