Fuzzy and Coco, the guinea pigs of Strawberry Park, London, are enjoying the spring, cleaning out their hutch and looking forward to the Easter fair! But then Fuzzy's owner, Ben, comes home very upset. The rescue center for local animals has to close down, and all because a very naughty bunny called Binny made a huge mess and chewed through all the cages! And, worst of all, the rescue center's Easter fair will have to be cancelled.

Things get worse when Ben brings Binny the bunny home to stay with the guinea pigs. Binny causes lots of trouble - she poops everywhere and is very rude to Coco. Meanwhile, Fuzzy and Terry, the guinea pig next door, plan to help get the Easter fair back on track by using the Internet to invite all of the locals to come help fix up the rescue center.

Coco and Eduardo try to help Binny improve her behavior, but she is too naughty to listen. She is a very sad bunny - she wants to be a pet in a home of her own, like Fuzzy and Coco. But then she runs off, and everyone is scared that the fox will find her and eat her!

The day of the Easter fair arrives, and lots of volunteers turn up to help fix the rescue center. It won't have to close after all! But where is Binny - the Easter Bunny? Fuzzy and Terry told everyone that she should be there! At the last minute, Eduardo and Coco find her, and they rush to the rescue center. It's not too late! Binny is adopted by a lovely little girl and the rescue center can stay open, and all because of the cleverness of the Guinea Pigs Online!
