Muck is one of Bob's machines from the Bob the Builder theme. He was first made into DUPLO in 3274 Bob and Muck Repair the Barn and 3276 Muck and Scoop, both in 2001.When Muck was first released (2001 in 3 sets) the rear dumper was supported by a single 2x4 plate. This meant the dumper fell off easily as it wasn't well supported. In all later sets the dumper is supported by two 2x4 plates put side by side.
