The cast of Bob the Builder, the children's television program which commands a legion of sub-teen fans around the world, will be joined this year by a mischievous forklift.

Named Trix, the forklift would arrive with Skip, a dopey truck, and cause headaches for the main stars with its pranks, according to The Sun.

The new characters would arrive at a time of change for the hit show, with two other new characters, Molly and JJ, the show's first characters from an ethnic minority, joining the cast. Molly was sensitive to green issues, and her father, JJ, was a building merchant, the report said.
