'''Bullet Bill Base''' (also known as '''World 6-6''', originally referred to as '''World 6-3''' in the E3 2013 demo) is the sixth main level in [[World 6 (Super Mario 3D World)|World 6]] in the game ''[[Super Mario 3D World]]'' and its [[Nintendo Switch]] port ''[[Super Mario 3D World + Bowser's Fury]]''.

==Layout==
This level features the [[Super Bell]] as the main power-up. It also features Conveyor Belts that only [[Cat Mario]] and [[Lucky Cat Mario]] can climb. The level begins near a wall that can be climbed, along with clouds that can be jumped on. A [[Galoomba]] is found at the top near four [[? Block]]s, along with [[Bill Blaster]]s firing [[Bullet Bill]]s. Moving clouds are found, along with a conveyor. More Galoombas and Bullet Bills are found. A group of crates is also found, one of which contains a [[Super Mushroom]]. A [[Sprixie]] with binoculars is found, along with a [[Warp Box]] leading the player to the [[Checkpoint Flag]]. A Galoomba, three ? Blocks, and four Bill Blasters are found, with a [[+ Clock]] on the platform above. A moving group of three Bill Blasters is found along a platform. A [[Hidden Block]] at the top of a nearby wall contains a [[1-Up Mushroom]]. More moving cloud platforms are found, with a [[Banzai Bill Cannon]] firing [[Bomber Bill|Banzai Bill]]s at the top of the area. Another Galoomba is found, along with more clouds and conveyor belts that can be used to climb another high wall. More Galoombas are found, followed by the [[Goal Pole]].
