Ernie’s a farmer trying to make ends meet, but no matter how hard he tries he can’t bring home enough corn to please his family and win the town’s annual harvest contest. And it doesn’t help that a bully farmer keeps jacking his crops. But this year something magical happens: two ninjas appear in his shed, and with their help he’ll reap his corn, best the bully, and win the long-coveted “Harvest King” crown. That is, if the ninjas don’t kill everyone first.
