i think we're inside Nonny's heart!!!
Deema and Goby imagine that they are doctors in the shrinking Star Wars-esque automobile and Nonny is feeling sick with a stomach bug, as Mr. Grouper as the doctor shrinks the two in the automobile in a cup and water and Nonny swallows the two, they went all way the way into the esophagus noticing many good bugs running away as Mr Groupers introduces that they help digest the food in the stomach. When they got there to the stomach, they see a large sized bacterium called the Stomach Bug and he stares at them, angrily growls and the two proceed to the lungs, the Stomach Bug chases after them and into the heart, again. And when they got to the mouth, they shrunk the Stomach Bug into the size of all the other good bugs, Deema scolds him saying that he is making Nonny sick, but the Stomach bug realizes and cries saying he is sorry for making the poor boy sick and wished he would help maintain his stomach. The two offers that he can help break Nonny's food down and join the good bugs, he then agreed, Nonny felt better and that was the end.
