Hatch Up Your Troubles is a 1949 animated short film (7 minutes) directed by William Hanna and Joseph Barbera.
It's a Tom and Jerry short. This one starts out with neither the cat nor the mouse but instead a mama woodpecker sitting on her egg. The mother leaves the nest to get food and naturally that is the precise moment where the egg hatches. The egg falls out of the nest and through some impressive good luck rolls right into Jerry's mouse hole. Jerry pulls the egg shell off and the baby woodpecker calls him "mama!" Jerry finds the presence of the phenomenally destructive woodpecker chick inconvenient, but the woodpecker won't leave him. Eventually Tom notices the woodpecker chick and then both Jerry and the woodpecker have to save each other.
Received a near-identical remake in 1955 as "The Egg and Jerry".
- Doorstop Baby: The egg rolls right through the door and in to Jerry's bed. Jerry is quite surprised to wake up and find a hatching egg under his covers.
- Efficient Displacement: When Jerry shuts the door on the woodpecker, it simply drills a woodpecker-shaped hole in the door and comes back in.
- Expy: The baby woodpecker appears to be one of Woody Woodpecker.
- Eye Pop: Jerry does this when, after thinking he has returned the baby to its nest, finds it right behind him inside the mouse hole.
- Hammered into the Ground: Tom gets defeated in this manner.
- Have a Gay Old Time: Tom reads a newspaper called the "Saturday Evening Puss".
- Imprinting: The baby woodpecker calls Jerry "mama", follows him everywhere, and refuses to go back to his nest. Finally at the end when the mama woodpecker shows up, the baby is able to change his allegiance.
- Low Clearance: As Tom is chasing after the baby woodpecker at top speed, Jerry sets out a rake at his neck level and Tom crashes right into it.
- Pint-Sized Powerhouse: The newborn chick can just annihilate wood. In one scene Tom flings a wooden rod at them like a spear and the chick destroys it in mid-air. Tom is defeated in the end when the baby woodpecker chops down a telephone pole so it falls on him.
- Tertiary Sexual Characteristics: You wouldn't think the mama woodpecker would need any since she was sitting on an egg, but she still has an apron.
