The school year is winding down, and Nate can't wait for summer vacation: baseball, beach trips, and... overripe bananas? Yuck! Turns out Nate has a problem with fruit that's past its prime. And that's not all that's bugging him. Kim Cressly is making Chester jealous at Nate's expense, Artur is challenging him in the Hunny Bursts mascot contest, and his replacement social studies teacher is none other than Coach John. In banana terms, it's all left Nate feeling a little bruised. Can he make it to summer without slipping up?
