Secret Agent Nonny is on a mission to deliver mysterious messages to all of his agent friends, which are actually invitations to his own surprise birthday party.
It's Nonny's birthday. Mr. Grouper pretends to be a secret agent. As soon as Nonny comes, he says that they were talking about geography. Then Molly sings Geography. Then they go outside and Molly and Gil recommend Nonny to pretend to be a secret agent. In the story segment,
Nonny goes to a magazine store where the shopkeeper opened a secret doorway, which led to a building. Nonny had a task to deliver several important messages. Deema gave him some tools; a flower which is actually a key to any door, a bowtie which could turn his car into a different types of transport, and camera goggles just in case he needs to take a picture.
He first had to go to the Swiss Alps. Nonny delivered the letters to Molly, Gil and Zooli. As Nonny was leaving, some Security Lobsters were chasing him. Luckily, he escaped with his bowtie by turning his car into a plane. Next stop was the Sahara Desert where Oona ang Goby are waiting. As soon as he entered their base, he asked "What time is it?" to Oona and Goby. It was time for lunch! Nonny got a burger with 'secret sauce'. He delivers the messages and exits the base. Just then, the Security Lobsters were chasing him again! He managed to take a picture of their hemlets and found out that they were the mysterious Dr. Bigmouth Bass' agents. He escaped once by transforming his vehicle to a helicopter and video called Mr. Grouper, but he was unavailable. He tried calling Deema but instead Bigmouth Bass answered. With the help from the viewers, Nonny found out that Bigmouth Bass was on an island. So he went. Just when he was about to open the locked door with his flower, he noticed that it was missing! Just then, the Security Lobsters came again and told Nonny that he had dropped it. Nonny wondered why they were being kind, he opened the door, and Mr Grouper was in there. And it was a SURPRISE PARTY!
