Nina is a small yellow cat-like dinosaur. She is short and has eyes similar to Jake's. Her head has two large, rounded bumps on it.
Nina behaves like a cat even with her Jake-like appearance. She is loyal to Gunther and follows him around, even though Gunther bullies her sometimes, similar to how Evergreen bullies him.
- Nina looks like a Protoceratops. A Protoceratops was a relative to the Triceratops which didn't have horns.
