Factory Tour is the sixth stage in both Kirby Fighters and Kirby Fighters Deluxe. The arena is based on the room that the player uses King Dedede in in the fourth stage of Shiver Star, the fifth level in Kirby 64: The Crystal Shards.
Factory Tour is based on the factory that appears in Shiver Star. The main hazards of the stage are Squeaky Hammer Machines that appear in the background. When activated, its porthole eyes will become red and the mouth will open up before it slams it hammer down. Squeaky Hammer Machines mostly activate one by one, but sometimes two will activate at the same time, leaving the third one to drop later. If the battle goes for long enough, all three will activate and drop at the same time, leaving very little room to dodge them. If a Squeaky Hammer Machine hits a Kirby, he will be flattened and slowly drift to the ground before returning to normal and being able to move again. This is either the fifth or sixth stage played in Kirby Fighters' single-player mode. The music that plays here is "Studying the Factory," the music that plays in the Shiver Star factory.
