The big day has arrived when Oggy gets invited to the marriage of his cousin, Jack, and a French poodle, promising to be cockroach-free, but Dee Dee, Marky and Joey come along for the wedding too ...

Oggy and Jack become lighthouse keepers for the day. While Jack gets a fear of heights, Oggy once again chases Marky and Joey, who have the book, while Dee Dee is directing boats all over the place.

Joey fools around with Oggy's bird-caller whistle, and attracts a cloud of grasshoppers, who invade the pyramid. The Grasshopper Leader does a deal with Joey, and ousts Pharaoh Bob.
