Tugboat Mickey
Mickey is performing routine maintenance on his tugboat (with interference from a pelican) when a call comes on the radio that there’s a sinking ship needing assistance. Sadly, Mickey’s crew consists of Donald and Goofy, so getting underway to help is not easy. Goofy has to fight a boiler’s door to get it stoked with coal (and when he succeeds, he overfills it) and Donald gets tangled up in the machinery. Not to mention that nobody casts off, so they drag half the dock along with them. The overworked boiler soon explodes.
Mickey, Donald and Goofy answering a distress call with a boat that is barely functional. The engine-room sequence is the centrepiece, and it is a good showcase for the trio dynamic — three men, one machine, three incompatible theories of how it works.
