Bob The Builder is a stop frame, animated series aimed at preschoolers (two- to five-year olds). Each episode follows the adventures of Bob and his machines: Scoop the leader/digger, Muck the digger/dumper, Dizzy the cement mixer, Lofty the crane and Roley the steamroller. Bob's business partner, Wendy, and Pilchard the cat also help out in the builder's yard. Other characters include Farmer Pickles, his tractor, Travis, and the naughty scarecrow Spud — who is always up to mischief.
