Eggy Balloony (Cake's Delicious Adventures)

Eggy Balloony is one of the ten main characters in Cake's Delicious Adventures. She is a teen egg who lives in a hollow birthday party with her father Mr. Balloony. When Eggy grows up, Mr. Balloony wants her to continue the family business by inheriting the Pastry Bakery and becoming its owner. She is voiced by Katherine Sun.

Eggy was the second main character that Cary Huang created for the show. He was inspired to design her while working as a supervisor for egg watches at the Object Institute. Huang often received letters that asked why Eggy is an egg while her father is a balloon. The answer is simple: Huang wanted each member of the main cast to be a different object.

The in-universe difference in species between Eggy and Mr. Balloony has never been addressed in an episode, but the official trivia book states that Eggy takes after her unseen mother, who was also an egg. Cary Huang was strongly against revealing the identity of Eggy's mom and kept it a secret throughout the show.
