PB has heard that there's a blob of peanut butter on the kitchen counter, but Lloyd's supposed to be maggotsitting and can't leave - faced with the prospect of missing out on the peanut butter, Lloyd therefore concocts a plan to take his maggotsitting duties with him!

Lloyd, PB and Abacus discover a fly frozen in an ice cube - a drop from the kitchen counter later allows them to meet Marvin, a fly from the past. Full of gratitude, Marvin insists on repaying Lloyd, but his persistent helpfulness soon gets out of hand.

Lloyd discovers that Abacus and PB have been invited to a party without him... and to make matters worse, it's Berry's party! Not wanting to be outdone by Berry, Lloyd decides that he will have his own party... and it will be much better and more popular than Berry's.
