Nonnyis a brainy, cautious, and overly calm male guppy. He's more likely to comment on the action than get swept up in it, and he often uses an advanced vocabulary for his age. His best friends are Oona and/or Gil. Physical activities make Nonny a little unsure of himself, he'd rather define "basketball" than play it.
His willingness to keep trying, combined with encouragement from his friends, often leads him to triumph in the end. Nonny loves to read books. His nickname is Nonners, although, nobody calls him that but Deema. His original nickname is "Mr. Cautious". He has the lunch jokes in most episodes. In Gup, Gup and Away! He had a lunch joke means a bangel and airplanes
