Giant - In her giant form she has the same face, a circular bumpy head, large hands with sharp nails, a pear-like body, and triangular feet. Normal - In her normal form she has a dark purple pear shaped body, light purple hair with flowers in it, golden circle-earrings, pink eyes being outlined by white and black pupils, light blue eyelids, visible eyelashes, a yellow nose, pink lips, light pink cheeks, a neckless strung with orange pearls, a top hat with flowers on it and pink feathers sticking out of it's top, black arms and legs, black hangs, and red boots. Her defeated form will crash into Majoliné and Bonmucho, and they will all fly off together. She is last seen after Galanmar is defeated. This will turn her into her defeated form, and she (along with Bonmucho) will travel away as the Earth creatures continue to sing their song. On it's final bounce, it will be thrown very high into the air, and then it will crash down on Majoliné and Bonmucho. This will make the bomb bounce off of them, and it will travel from zone to zone while Majoliné sits on top of the Earth. Just when it's about to make impact, the creatures make their own song to counteract it. The creatures on Earth will stare on in horror until she reaches space, where she then throws the bomb back down to Earth. She will shortly come to her senses, and rise into the sky with the bomb. Irritating her eyes will make her even more angry, struggling to get the words out of her mouth. During this fight, more Moja will appear to try and stop you, and at some points she will reach out to grab parts of the LocoRoco. They will arrive on her face and fight her by pocking her eyes, gradually making them more and more red.
After they reach the Muck Bomb, they will need to make their way out until they fall onto Majoliné. Bonmucho (in his defeated form) will attempt to kill the LocoRoco with the help of other Moja until the platform reaches the Muck Bomb. Once the LocoRoco arrives, they will hop onto a platform that will begin to travel into the air.
In the next mission, her muck bomb has become so big that surrounding objects are beginning to levitate to it and detach from the ground. This will make her fly away, but she will stay in this zone. The LocoRoco will need to make their way to this machine, knock them off, and then sing their own song. Here, she will be working on making her Muck Bomb through the help of her fellow Moja, whom are using a BuiBui machine. She will eventually fly away, and move onto the Dolangomeri area. Near the end of the level, the LocoRoco will need to hide behind a bush to avoid her. She becomes angered after it is charged, and she flies away. Once there, the LocoRoco will need to jump inside of a magnet charger machine and make it turn on by bouncing around it. Once she is transformed, she will travel to three different locations, and the LocoRoco will have to scare her away. More Moja appear around her to help her sing. Once transformed she beings singing, and a ball of muck appears over her. She becomes so angry that she begins her transformation into her giant form, destroying her home in the process. She angrily takes her head out and she wipes it off as they explain that they were defeated by the LocoRoco. Later, after her BuiBui were defeated, they crashed through her window and made her face-plant into her cake. She forgives him, then commands her BuiBui and some Moja to go take care of the problem.
She stares at him in anger until he comes back to his senses and explains to her the situation with the LocoRoco. His defeated form bounced through her window, landed on her table, and ruined her cake. She is later seen again after Bonmucho was defeated for the second time. She takes out her umbrella, commands her BuiBui to hop on, and then she to files away. He and Majoliné share a few words until he flies away. Once they do, it shakes around and then Bonmucho pops his head out. They retrieve them, put them in, and then she commands them to turn on the machine. She commands them to put him into the machine, and then tells them to gather his various dyes. After passing through various worlds, they finally reach Majoliné standing next to the machine. Offscreen, some of these BuiBui were commanded to drag the defeated form of Bonmucho to a machine that would turn him back to normal. When the LocoRoco entered the Dolangomeri area, they had to hide underneath a tree while a BuiBui carried Majoliné in a carriage with their robot suit. Once their transformation is complete, more BuiBui appear around the screen and they celebrate. Their body begins to turn red, and they transform into a BuiBui. She opens it, takes them out, and kisses them. She approaches a panicking MuiMui who is locked in a cage. She is first seen right after Bonmucho is first defeated.
