'''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]]''. This level is unlocked along with [[Ty-Foo Flurries]] after completing [[Prince Bully Blockade]], and completion of either this level or Ty-Foo Flurries opens [[Fuzzy Time Mine]].

==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]].

==Collectables==
===[[Green Star]]s===
*'''Green Star 1:''' The first Green Star is on the highest point of the first section of the level.
*'''Green Star 2:''' The second Green Star is found in a [[Mystery Box]] near the [[Checkpoint Flag]]. The player needs to follow a circular conveyor belt on the wall in a time of ten seconds to reach it. Using the Cat form makes it much easier to reach the Star.
*'''Green Star 3:''' The third Green Star is found near a row of vertical conveyor belts near the end of the level. The player needs to climb up the one farthest to the left, then take the one on the top that carries the player to the right onto a platform with the Green Star.
