Grunty Industries

Grunty Industries is the sixth world of Banjo-Tooie. It consists of a giant pollution-spewing factory and the area around it. Given its name, it's possible that Gruntilda is its CEO. The entrance to the world is in the Quagmire, and is easily visible and accessible.

One of Grunty Industries' signature frustrations is that, upon first entering the world, it appears impossible to enter the factory proper: the main entrance is closed, and all other entrances are out of reach. The key is the Train Switch concealed behind the access shed on the right side, which opens the Train Station inside Floor 1. Once the player takes Chuffy in from another world, they then have full access to the factory, though they must still press a pair of split-up switches to open the main entrance for later convenience.

Architecture
This industrial zone in outside is a building with 5 floors, 3 roofs with 4 fans, 2 chimneys, 59 windows, front door, 4 emergency exits, sewer pipe and power cable. Inside contains a basement, machineries, toxic waste, depots and attic. In different floors contains a train station, quarters, water disposal plant, trash compactor, air conditioning plant, electromagnet chamber, boiler plant, packing room, cable room and sewer access.

Banjo Tooie
In Banjo-Tooie, the duo entered this factory in Chuffy, Mumbo Jumbo had to jam all the machines with EMP, here the pair is transformed into washing machine and occurred the battle with Weldar. The industries started enter in downhill when the pair sabotaged all systems and defeated Weldar who was protector this complex.

According to the shortcuts, this building was the cause of many problems on the whole island. For example: the pollution with toxic waste on the Jolly Roger's Lagoon, water sucked on this same place and oil drained in an pumpjack from Hailfire Peaks's ice side.

Banjo-Kazooie: Grunty's Revenge
In Banjo-Kazooie: Grunty's Revenge, a "very young" (as described by the Jinjo Oracle) Grunty Industries appears as a sub-area of Freezing Furnace. Klungo is fought in the place, and Banjo can become a tank with the Mumbo Totem he drops alongside the Jiggy.

Banjo Pilot
In Banjo-Pilot there is a course also named Grunty Industries, and the eponymous building appears in the background.

Banjo-Tooie

 * 1) From the Water Supply Pipe in Jolly Roger's Lagoon in the Smugglers' Cavern.
 * 2) On Floor 2, next to Humba Wumba's tent is a vent. Break open the vent with a Grenade Egg and walk in. The Jinjo is in a hole that is out of reach. Use the Split-up Pads and get Kazooie to Glide or use the Claw Clamber Boots to get to Jamjars. He will teach Kazooie the Leg Spring, which then can be used to get the Jinjo.
 * 3) Go to the roof. You will see a metal plate patch on the left smoke stack (if you're standing on the flight pad, it will be the one to the left of Banjo & Kazooie) Use the flight pad and use the Beak Bomb move to break open the metal plate. Once inside the stack you will be able to release the Jinjo.
 * 4) Use the Split-Up Pads, then take Banjo out the fire exit for the 1st floor. Once outside to your left you will see a box that you can break. Once the box is broken you will then see a silver button Banjo steps on that will open the window leading you up to the Orange Jingo. Next switch characters and leave banjo on the button to keep the window open. Have Kazooie either use the flight pad to go up the building or use the Claw Clamber Boots to climb up the building. The window that Banjo just opened to release the Jinjo is located up the side of the building to the right of the fire escape while looking at the door/building.
 * 5) In the attic, get on the roof then Bill Drill through the left window (left when facing the smokestacks).

Banjo-Kazooie: Grunty's Revenge

 * 1) On the toxic waste, only accessible with Tank Banjo.

Empty Honeycombs

 * 1) Inside the Train Station on Floor 1, there is a platform in which you can walk on. At the end of the platform is a Rare box. Inside is a Shockspring Pad, break it open and then jump up and grab onto the rail above you. Across the rail is the Honeycomb.
 * 2) On Floor 3, make your way up by climbing on boxes near the Boiler Plant door. In the corner is a breakable box, which has a Shockspring Pad inside. Jump up onto the higher stack of boxes and there should be another breakable box. Inside is the Honeycomb.
 * 3) On top the Un-Enterable Smokestack

Cheato Pages

 * 1) Activate the Flight Pads (Found on Floor 4) and smash open the nearest window from the Flight Pads to the right of the entrance. Inside the window is a room with a Cheato Page.
 * 2) Go to the Workers Quarters on Floor 1. On the wall to the left when facing from the door to Floor 1 where the poster of Jet Force Gemini's Vela is, there are two doors. Blast the door marked as "Men's Bathroom" with a Grenade Egg and walk inside. Talk to Loggo and then Bill Drill the inside of his bowl. He will reveal a Cheato Page.
 * 3) After defeating Weldar, the spindle above the room will stop rotating. Use it walk to the other side of the room and collect the Cheato Page on the platform.

Treble Clef
On top of the factory entrance, use the flight pads (alternatively shoot a Clockwork Kazooie egg while airborne), Kazooie's Glide move, jump from the top of the building (best you have the FALLBACK cheat before trying this), or fire a Clockwork Kazooie egg from in front of the entrance (this is very tricky to get just right).

Trivia

 * By using a glitch, the player can enter in Grunty Industries without Chuffy.
 * In Banjo-Kazooie: Nuts & Bolts, Grant Kirkhope composed a music track for a world that included the theme to Grunty Industries. It ended up being unused.
 * Loggo makes a cameo appearance in the men's bathroom in the worker's quarters.
 * This is the only world in Banjo-Tooie which requires Banjo and Kazooie to defeat an earlier boss before fully exploring it.
 * In the room where the Jiggy on the fan is, there is a door that can't be used.
 * Scattered throughout Grunty Industries (notably, the Quality Control Room) are wooden crates which have "DELIVER TO TWYCROSS ENGLAND" written in bold letters on their sides. This is a nod to how Twicross, England is where the Rare Ltd. headquarters is located.
