Bears

There are a group of bears that are in charge of making sure every toy is gathered up and put onto the Birthday Train before it is delivered to whoever's birthday it is in the 1991 film and the Tom and Jerry version of the film. They are only seen once putting the toys on the train and are never seen again throughout the remainder of the film. Tom and Jerry & The Little Engine That Could adds a backstory to the Birthday Train, where the bears are repaired and painted an old train of cars at Screwy Squirrel's Workshop.
