There are 3 main villeins apart of tina's story. Mafia squirrel. A animal you meet every once a while in the game. 2D Jr. The son of 2D wizard. And the person I just mentioned. the 2 of them are 2D dimensiol and whatever they cast a spell on turns 2D dimensiol. You travel in Iceland ( starting place ), France, England, Canada, China, Japan, Madagascar, Zimbabwe, Australia, Sea land, Brazil, Peru, USA, Romania, Italy, Russia and Antarctica where 2D wizard's lair is. The same old thing happens and they escape. Sid's story is the last real story of the series. A skull that travels with a human, and a living parasite. They must defeat the most wanted person alive named ballard, A evil knight who crushes skulls and bones. The planet is called 2202 which is a variation of earth in the Apocalypse. The game plays like undertale where you make choices either pacifist or genocide. When you finish walking through many mansions and forests, You are facing a very high mountain where you fight ballard in pacifist route if you choose to run away from him away from the final mansion. If you choose genocide you fight him in the last mansion you enter and fight him as a zombie. The boss fights in pacifist run is where you run away until they get exhausted and try to set up traps. After all those events all the villeins are in space where all the characters are defeated except for a sudden penguin named thief. A secret agent penguin who steals from thieves. The level you are in is all the games into one and the environment is all mixed up since the 4 worlds collided. The 4 villeins create a machine that can fuse them. And they become the "SUPREME FUSION". The real final boss you fight as thief. After you defeat the Supreme fusion everything goes normal again
