Super Mario Castle World

 is a game released on the Nintendo Ultra-64. It was known as Super Mario 64 IOTL.

Story
"Please come to the castle. I’ve baked a cake for you."

At the invitation of Princess Peach, Mario (along with Luigi) enters the Mushroom Castle.

Upon entering the castle, Mario and Luigi discover that no one is there. According to Toad, some maniacial Toad has stolen the Power Stars guarding the castle and locked Princess Peach into the walls and paintings due to jealousy & power hunger. That mysterious Toad goes by the name of Fungüse!

Now it’s up to the Mario Bros. to rescue Princess Peach and their friends from the castle’s paintings and walls!

Gameplay
The gameplay is identical to regular Super Mario 64, except this time, Mario and Luigi are here. Mario plays the same, except his punches and kicks are more powerful, letting him knock back enemies further. On the other hand, Luigi has his trademark higher jump. Wall jumps are done by jumping towards a wall, holding the joystick against said wall to slide down, and then jumping again to an adjacent wall to repeat the process. Back flips are done by crouching, then jumping. Long jumps are done by crouching, then jumping immediately. Jumping 3 times while running allows a triple jump, with each jump going higher.

 * Money Bags: Defeat it for coins, but it is elusive.
 * Motos: A robot that acts like a combination of Bully and Chuckya. It has a dash attack that can push the player off platforms in 1 punch, which takes 30 seconds for it to recharge. During recharge, it can throw the player when it gets close enough.
 * Mad Cue Ball: Living cue balls who are busy playing a game of pool. If the player approaches them, they attempt to squish them by retracting their arms and legs and rolling since they think the player is attempting to disrupt their game.

 * Whomp: Thwomp's flat cousin. It walks around and upon seeing the player, it jumps and falls on its face, exposing a spot that can be ground pounded to defeat it.

Bosses

 * 1) King Bob-Omb: King of the Bob-ombs. Go behind him, pick him up, and throw him a few times. After so, he says that he will return for a rematch.
 * 2) Whomp King: The giant king of the Whomps. Attack him the same way Mario and Luigi do to regular Whomps. Difference is that he needs to be struck thrice and his range of flattening is bigger.
 * 3) Goomboss: The large king of the Goombas. Summons Goombas for protection. Punch them towards their king. After he takes 3 hits, he summons the larger variant of Goombas, which take 3 punches to knock away. After getting hit by a large variant, the pattern repeats. After 3 loops, he is defeated.
 * 4) Bowser: The king of the Koopas tricked by Funguse. He attacks by stomping and breathing fire. Defeat him by picking him up by the tail and then throw him at the floating mines for a certain number of times. Afterwards, he realizes the truth and gives the player the key to the Basement.
 * 5) King Boo: Back for revenge, the ghost king has new tactics up his sleeve. He can summon Mr. Is to shoot while he sends down ghost fire. Defeat him by throwing Grab Blocks at him when he gets to ground level.
 * 6) Big Mr. I/Unblinking I: Identical to a Mr. I, except bigger and can shoot triple shots. Run around him, then run the opposite direction. Do this thrice and he is defeated.
 * 7) King C. Ue Ball: The king of Cue Ball Chaos. He pretty much thinks that the player is attempting to ruin the game of pool. He attacks the same way as the Mad Cue Balls, but his rest rate is much shorter, which is 10 seconds. After the cooldown, he summons a Mad Cue Ball to attack alongside him. After attacking him 3 times, he calms down and gives the player a "thank you" for a challenging fight.
 * 8) Big Bully: Exactly the same as a regular Bully, except bigger and harder to knock off the platform. There are 2 of them that reside in Lethal Lava Land.
 * 9) Eyerok: Shifting Sand Land's guardian. Its hands attempt to knock the player off the platform. However, each hand has an eye in its palm. When said eye is exposed, it needs to be punched 5 times to destroy a hand. Once both hands are destroyed, Eyerok falls asleep and becomes a dormant statue.
 * 10) Wario/Waluigi: Both are under the spell of Funguse to guard the Fire Sea, and the battle takes place in a caged arena. Wario fights Mario while Waluigi fights Luigi. Both of them throw bombs, punch, kick, and even attempt to stomp the player. Both of them have the same properties as the Mario Bros. (with Wario having stronger punches and kicks for knockback while Waluigi has higher jumps for unpredictability. They need to be hit 5 times. Afterwards, they snap out of the spell and the portal to the Fire Sea opens.
 * 11) Salamandragon: An ancient wingless fire-breathing dragon resurrected by Funguse. Its tail is to be grabbed and then it is to be thrown to the mines. However, Salamandragon can shoot fire in 3 directions and tip the arena by ground pounding.
 * 12) Chill Bully/Chief Chilly: The king of cold. He acts the same as the Big Bullies, except the lava is now replaced with water so cold that it acts like lava. Defeat him the same way a Big Bully is defeated, but knock him into the freezing water thrice.
 * 13) Giant Wiggler: The only Wiggler to reside within Tiny-Huge Island. His temper rose when the player accidentally flooded his home. Stomping his head twice makes him go faster and the 3rd stomp calms him down, shrinks him, and he leaves the arena.
 * 14) Powered Fungüse: Infused with the Power Star that keeps Peach locked away within her castle, the Toad behind this has been transformed into a monster that resembles a hybrid of a Toad and a Koopa. His attack style is similar to a combination of Bowser and Salamandragon, along with shockwave stomps and making the arena fall apart. He is defeated the same way, which is grabbing him by the tail and then throwing him to a mine.
