After about a week or two of sitting on her egg, Mayzie persuaded Horton to sit on her egg for a few hours, while she actually flew to Palm Beachand decided to never go back until Horton was done. When Horton was sold to the circus, causing him to arrive at Palm Beach and Mayzie saw the show, bumping into Horton in the process. When the egg is about to hatch, she demanded the egg back without offering Horton a reward. The bird soon hatches and is a cross between Mayzie and Horton. Horton is rewarded for his hard work by keeping the "elephant bird" and Mayzie is punished for her laziness by getting nothing. As she pouts on the side, a man who came in the tent with the others spots her for an unknown reason as the others are being entertained by the new discovery of the elephant bird. However, in Seussical the Musical, Mayzie decides to give Horton full ownership of the egg, admitting that she would not be a good parent and Horton would be a better parent.
