There is a turtle expert visiting the Safari World aquarium. Mr Hammond is on a scuba diving holiday in Borneo, so it’s up to Andy to ensure everything is ready for their arrival. Andy does a great job making the aquarium looking its best, but when Mr Hammond asks Andy if he has cleaned the green sea turtles, Andy is a little confused as he thought they cleaned themselves. Mr Hammond informs Jen and Andy that green sea turtles get clean by letting little fish nibble away the dirt and parasites on their skin and shell. However, he neglects to tell them what kind of fish, so Andy decides to find out for himself. It’s time to go on an aquatic adventure! Andy blasts off through a magic portal in his safari-sub and heads to a beautiful coral reef off the coast of Borneo
