Toto (Rolo in the English dub of the third film) is an anthropomorphic egg whose personality is shrewd and sympathetic, but seriously separated from his mother and imported into a store. He is the key protagonist who has a good relationship with Willy and Biba. In the third film, Toto is actually a rooster.
One of Toto's dislikes is once Serp starts to attack his friends. Serp is usually very despicable in confronting Toto. Toto also dislikes the cat, because the cat has a big appetite for eggs. He also dislikes why an evil egg sorcerer was commanding his scorpion armada to take over the world.
