Dizzy is an orange tilting-drum concrete mixer. Dizzy is portrayed as one of the youngest vehicles in Bob's building yard. She is eager, curious, and easily excitable.


Dizzy is a smart, witty, and eager concrete mixer. She can be a bit of a know-it-all, spinning her mouth as fast as her drum. This sometimes leads to mix-ups, but her energy and enthusiasm make her an integral part of the team.


Dizzy is energetic, curious, cheerful, and a bit of a know-it-all, like Roley she seems to enjoy music but only listens to music. In the original series, she has the ability to stand on her rear tires similar to how dogs can stand on their hind legs. She does have a soft spot for friends and she is always ready to lend a helping hand.


Dizzy is a small, orange tilting-drum concrete mixer. She has an orange mouth and big, round eyes, and small tires, which she is able to clap while happy. She also has a black stripe across her mixer drum.
