'''World 4''' is the fourth world in ''[[Yoshi's Island DS]]''. It takes place in the mountains of Yoshi's Island, becoming snowier and colder in the second half as Yoshi scales greater heights. In World 4-5, [[Baby Bowser]] encounters [[Yoshi]] and his party, and decides to join them on their adventure. However, this alliance is short-lived, as at the end of the world, Baby Bowser abandons the party as he attempts to go off with [[Kamek]]. World 4, like all other worlds in the game, has a total of ten levels; six regular, two hidden, and two bosses. The bosses in this world are [[Six-Face Sal]] and [[Big Guy the Stilted]].
