Mad Monster Mansion

Mad Monster Mansion is the seventh world of Banjo-Kazooie. The entrance to this world is located in the Graveyard section of Gruntilda's Lair; this area is past the "Lava Room" on the sixth floor of Gruntilda's Lair. Its picture is located on the seventh floor, specifically the third room you enter through underwater passages. The picture requires 10 Jiggies to complete.

Jiggies

 * 1) Enter the Well: A Jiggy is located inside the well. This Jiggy is accessible as Banjo or the Pumpkin transformation.
 * 2) Copy Motzand's Tune: Gain access to the church by Beak Busting a clock switch near the Blue Jinjo's location and running to the entrance before the door closes. You will need to equip the pair of Turbo Trainers and break down the gate leading into the churchyard to enter the chruch. Once inside, climb up to the organ's scoresheet and Motzand will begin playing keys on his organ. Beak Bust the keys he plays in the order he plays them and after 2 sessions, he will dissipate and a Jiggy will apear at the top of the organ.
 * 3) Clear the Tumblar Minigame.
 * 4) Help the Pots: Around the churchyard are 5 brown pots. Shoot Eggs from Kazooie's behind into each pot and a Jiggy will pop out of the last one.
 * 5) Scale the Church: At the top of the church tower. Use the gravestone near the entrance to climb up.
 * 6) Nab from Napper: Ascend to the very top of the mansion and fall through the chimney. Once inside, jump across the chairs onto the dining table without landing on the creaky floor below. Once on the table, simply walk through Napper to collect the Jiggy. If the player attempts to enter this room through the front entrance or the player lands on the floor, Napper will solidfy and the Jiggy will be unobtainable until the duo leaves the room.
 * 7) Break the Barrels: Beak Bust the hatch leading into the cellar just outside the churchyard gate. Inside the cellar, break open the southernmost barrel on the left to find the Jiggy.
 * 8) Inside Loggo: Break open the window on the second floor, using a Rat-a-tat-rap, that leads into the bathroom. Afterwards, transform into the Pumpkin and ascend to the second floor of the mansion (a small gap near the hedge maze in the churchyard leads to a ramp, granting access to the second floor and is also required for Jiggy #9). Enter the bathroom and jump into Loggo. You will be flushed into the sewers and the Jiggy will be between several Whipcracks and Grille Chompas.
 * 9) Inside the Gutter Basin: Using the same ramp from the previous Jiggy, access the second floor of the mansion as the Pumpkin and locate a small hole on one of the corners of the gutters. Sit still on the hole and you will fall into the basin below. The airborne Jiggy will be collected as you drop in.
 * 10) Find all 5 Jinjos.

Extra Honeycombs

 * Inside the second floor room, opposite the bathroom. You will need to access this room as the Pumpkin as the Honeycomb Piece is under the floorboards. (Use the same technique from Jiggies #8 and #9 to reach the room.)
 * Hovering over the wooden rafters inside the church.

Witch Switch

 * Located on the rafters of the church. This spawns a Jiggy in one of the eyes of the big Grunty statue on the sixth floor of Gruntilda's Lair (the room with cobwebs). Either use the Flying Pad from the Freezeezy Peak Witch Switch Jiggy to obtain it, or simply jump down from the brim of the statue and Rat-a-tat-rap the glass to collect it.

Mumbo Tokens
Due to a mistake in the programming of event flags, the Mumbo Tokens marked with (*) are treated by the game as the same Mumbo Token, meaning that collecting one will cause the other to disappear. This essentially means there are a total of 116 Mumbo Tokens in the game, though only 115 are obtainable.
 * In the Hedge Maze.
 * On top of Tumblar's Shack
 * In the left fire flame inside the Dining Room's fireplace.
 * In one of the 1881-marked barrels in the cellar. *
 * Inside the septic tank. *
 * In the well.
 * Behind a gravestone by the Haunted Church.
 * Inside the church clocktower.
 * In the bathroom sink.
 * In the bedroom with the Yellow Jinjo, hidden behind a dresser.
 * On the narrow middle section of the church rafters.
 * Under the Whipcrack guarding the Blue Jinjo.
 * In a corner near the fountain.
 * In a corner near Tumblar's Shack.
 * Next to the small hedge ramp where the Pumpkin ascends to the second floor.
 * On the stool inside the church.

Extra Lives

 * On top of the chandelier in the Dining Room. Use the Flight Pad to reach it.
 * In the Haunted Church, behind the organ pipes.
 * Locate a stained glass window towards the back of the church with Banjo and Kazooie's faces on it and jump into it. An extra life, among other items, can be found in here.

Banjo-Kazooie: Nuts & Bolts
"Spine-tingling area of Banjo-Kazooie where our heroes met Loggo, a dozing ghost called Napper and an organ-playing spectral hand named Motzand. Was it Grunty's holiday home? Who knows?"

- Banjoland description

Though it does not physically appear in Banjo-Kazooie: Nuts & Bolts, an incomplete replica of the mansion appears in Banjoland, along with its own graveyard. Its nature of incompleteness is also referenced by Bottles, as in one of the missions, you were supposed to complete the mansion exhibit by lifting the pieces with the wrench and placing them on the square shaped white patch. However, this was ultimately scrapped and an air race took its place instead. He even states that the delivery van that had mailed the parts had accidentally emptied them into Loggo and they went straight to the Cut For Deadlines Room.

Trivia

 * This is the first and only world in Banjo-Kazooie that contains two Stop 'n' Swop items: the Green Mystery Egg and the Cyan Mystery Egg.
 * When Grunty is kidnapping Tooty, this stage's music can be heard sped up.
 * The Flight Pad under Napper can be used even without speaking to Bottles in Treasure Trove Cove.
 * The church in Mad Monster Mansion is modeled after the real church in Twycross (the home base of Rare).
 * Mad Monster Mansion's entrance in the beta version of the game was thought to be opposite Freezeezy Peak, behind Gobi's Valley or in the water level raising room.
 * The 1881 keg sealed with an X, which contains the Cyan Mystery Egg, is a reference to , one of Rare's first games.
 * Because of the way the Flower Urns talk, people often mistakenly hear the pots say something else of vulgar nature. Rare Ltd. has mentioned that this is untrue and that the pots merely say "Thank you". Grant Kirkhope, the voice actor of the urns, confirmed this on a special episode of "Game Grumps", called "Guest Grumps", on YouTube. He also stated that it took many takes before the current utterance of "Thank you" was accepted as being clearly audible.
 * Some portraits in this world featured the Pirate, Captain Blackeye who was the original villain for Project Dream before it became Banjo-Kazooie.
 * The music for this level was originally going to be in Project Dream under the title "Bully". Parts of it also were to be in the piece "Chase"
