Bob the Builder: When Bob Became a Builder (2006)

While building a new picnic area at the beach, Bob and the machines tell Benny and Scrambler the story of how he got started as a builder. Bob then recounts he and his dad Robert constructed the building yard in Bobsville, and how the machine crew we all know and love got together. Once the picnic area is finished, Benny and Scrambler agree that it's brilliant to be part of Bob's team!
