Zooli is a spunky and smart character, animal expert and fin-tastic friend to the guppies' school class.
She is shown to be clever, as seen in The New Guppy! when she tricks the Sea Witch into turning the latter into a sea dragon.
She is also shown to be sympathetic to others, as seen in Dragons N' Roses! when she was the only person in the Kingdom of Roses to go to Agnes the dragon's cave to find out what was wrong.
Zooli has dark skin and dark brown eyes. Her curly indigo hair is held up in a bun and has a blue seashell on the side. Like Oona, she has a full-pieced tail and almond shaped eyes. Her pink tail is spiraled.
