Jackhammer is a boss in the 1999 video game Toy Story 2: Buzz Lightyear to the Rescue.
The Jackhammer is the boss of the game's fourth level, Construction Yard. It is a tall and intimidating drill tool that is fought at the very top of the metal construction tower. It will chase after Buzz along the narrow girders attempting to hurt him, and due to the limited amount of space, it is quite easy to fall off. The Jackhammer is only vulnerable to the Disk Launcher (given to Buzz by Mr. Potato Head), as a regular laser does no damage to the boss. The Jackhammer also has a tendency to throw burning nails at Buzz from a distance, again threatening to knock him off the edge. Once the Jackhammer is gone, Buzz will get a Pizza Planet Token as a reward.
