Scratch is a 4 year-old small, blue skid-steer loader, whom is also the youngest of the team. He only appears in Ready, Steady, Build!
Scratch greatly resembles Benny, except he's blue instead of magenta and doesn't have a back bucket
Scratch is childish and very naive. Scratch still has a lot to learn such as learning how to stand up for himself, asking for help, etc. Scratch loves to work and says he's a part of the team.
- In the Finnish version, Scratch is called "Kätsy".
