Dizzy is an orange tilting-drum cement mixer. She is the youngest vehicle in Bob's building yard. She is eager, curious, and easily excitable.
Dizzy is a smart, witty, and eager cement 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 enjoys 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 cement 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.

Dizzy is able to use her wheels like hands or feet in the original series.
She had a walkman which was later removed in Project: Build It, though it reappeared in When Bob Became A Builder.
Dizzy's original movement sound is a simple squeaking sound effect.
Dizzy can also use her wheels to pick things up and throw them, as shown in Mucky Muck.
Dizzy was the youngest machine in the original series before Trix was introduced.
Dizzy is the only machine character to appear in every episode in the second season of Ready, Steady, Build!.
Dizzy is female in all versions except for the Romanian version in which Dizzy is male.
It is unknown if she and Scratch are siblings.
In the Finnish version, Dizzy is called "Hyrre".
