Principal characters •
Mother Goose: Could be considered the hostess of Rub-A-Dub-Dub. She begins every episode by saying "Rub-a-dub-dub, there's a... in the tub." She is a white goose, wearing what looks to be a yellow raincoat and hat, a blue skirt beneath the coat and blue shoes. She also wears pink tights with white spots. •
Polly: An irritable parrot. Their gender is ambiguous, as the song "
Little Poll Parrot" refers to them with male pronouns while the song "Mrs. Mason Bought A Basin" refers to them with female pronouns. They often get annoyed with various characters, such as with Mother Goose when
she asks them to make King Crow's tea. In this instance, they respond "I'm not gonna make it! Why does it always have to be me!? Humph!" They also often appear to be on the receiving end of bad luck, such as when they set their dinner down before the television, leave to get a drink, and then find their dinner has been stolen, to which they respond: "EH! Where did it go?!" Polly had a red face and blue hands and legs, wore a green jumper with red sleeves and yellow shoes. •
King Crow: The King who is a crow. He was awfully demanding of his servants such as Polly, on whom he intrudes into their TV-watching time, saying "Hello Polly,
get me my pipe and bowl please!" He was also awfully energetic and bounced around a lot. Like all crows, King Crow was black with a yellow beak. He wore a stereotypical King's robe and crown, black and white striped stockings and black-and-white shoes. •
Queen Duck: The wife of King Crow. She was featured as
The Queen of Hearts. She wore a blue dress with a red heart on the chest and heart-patterned sleeves. •
Al E. Gator: An alligator who was somewhat of an antagonist on the show. He was always causing trouble, such as tripping over Baa Sheep and causing him to fall in mud, or interrupting Polly's favourite TV show as "Tonight's Special Guest". He wore a red coat and a top hat. In one episode, he lost his violin bow. He does have a good side though, as he helped nurse Yankee Doodle back to health when the latter knocked himself out after doing his morning exercises. •
Baa Sheep: A white sheep who wore red shoes. He once fell victim to Al E. Gator's mischief, when he tripped him over and caused him to fall into a muddy puddle. This
dirtied his wool and left him displeased. He sang
I do not like thee, Doctor Fell to him. Al E Gator simply laughed and asked "What did I do wrong?" before leaving. Baa was also close to Mother Goose, who cleaned him up in the eponymous tub after this incident. •
