Rolly Roll is one of the protagonists in the game Billy Hatcher and the Giant Egg. She, along with Billy, Chick,, were sent to Morning Land to save the Chickens Elders from Dark Raven's forces. She was sent to Pirates Island where she obtained a Chicken Suit and tried to defeat the Crows, but was defeated herself and tied to a bomb. After Billy saved her, she became playable in the main game with her own unique mission for each world, much like Chick and Bantam.
A lighthearted and carefree girl. She always tries to help others who are in trouble, but can sometimes be a bit "scatterbrained".

- Rolly has the smallest chicken comb on her head.
- She and Bantam have noticably different coloured helmets.
- Her character strongly resembles that of Amy Rose from Sonic The Hedgehog.
- She is given the same voice clips for most of her actions; whenever she jumps, dashes or drives she always shouts "Ay!".
