Big Super Happy Fun Fun Game

Big Super Happy Fun Fun Game is the fourteen level of The Simpsons Game. To open the door to the creator's mansion, the Simpsons have to get the four keycards in the four worlds created by the creator. The fourth portal transports Homer and Lisa to a Japanese land and dresses them as Japanese cartoon characters.

Description
After the level "Bargain Bin" is completed, four more levels open up at the game engine. These can be taken in any order but, following the story, this is the next level.

Plot
Homer and Lisa encounter themselves in a Japanese land, with flowers with happy faces, rainbows and a town. Later, a giant Milhouse wearing a crown and big drums-like things in his ears appears from the water, saying he is the king of the land and is called "Mr. Dirty". Homer and Lisa walk up a path to a dirty brown river coming from a clean waterfall that leads to the town. Beyond the river, everything is dirty, including the floor, the houses and a giant toilet on a brown lake. The toilet has a big rock head shaped like that of Homer's. To free the head inside, Lisa has to find three lanterns and position them on their spots so they shoot a light to the head. She uses the Hand of Buddha to pick up the lanterns and also defeat the sumo wrestlers who come from the lake. Once all the lights are on their spots, Mr. Sparkle (the Japanese head from "In Marge We Trust") is freed. He tells them that to clean Mr. Dirty's land, they will have to defeat the three Sparlkemons in three more lands parallel to Mr. Dirty's. Homer and Lisa go to the lava land, conformed by lava and moving wooden platforms. They first defeat the lava sumo wrestlers and then cross a lava ocean using a tree, cut down by Homer as "Gumi-Homer", as bridge. They get to the lava well, where Jimbo waits for them. Now they all have a Japanese cartoon-style fight in which Homer and Lisa defeat Jimbo's Sparklemon and, after Mr. Sparkle eats the creature and Mr. Dirty (on a cloud) comes to tell them they won't defeat any more Sparklemons, Homer and Lisa go to the ice land, conformed by cold water, ice floor and a giant yeti inside an ice block. Before getting to an upper floor, they defeat the ice sumo wrestlers. They jump into the ice well where Ralph and his Sparlemon fight Homer and Lisa. When they win, they walk across a rock bridge to get on a flying boat. It has five motors keep the boat floating. Another flying boat floats next to the big one and cloud sumo wrestlers come from it. They turn off the motors and Homer and Lisa have to stop them before the boat falls down. When they finish with them, the sky well appears on a big cloud next to the boat and Sherri and Terri are inside with their Sparklemon. Homer and Lisa defeat it and Mr. Dirty goes away crying when he sees this. Homer and Lisa then insert the three Sparklemon balls inside the toilet to make Mr. Sparkle raise on a water fountain. He cleans the town (by rubbing the screen) and Mr. Dirty shrinks to become normal Milhouse. He gives Homer and Lisa the Mr. Dirty keycard before the three Sparklemons attack him.
