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?
