Sequels and Spin-offs
The semi-sequel Yoshi's Story was released for the Nintendo 64 and featured similar gameplay, but is generally considered to be of a lower quality. The series has seen two spin-offs: Yoshi Touch & Go for the Nintendo DS and Yoshi's Topsy-Turvy for the Game Boy Advance. While unrelated in basic gameplay, the characters and graphical style are heavily based on those of Yoshi's Island.
Yoshi's Island DS, released on November 13, 2006 for the Nintendo DS, is the most direct sequel and incorporates many of the same gameplay aspects. Unlike Yoshi's Island, it now also features Princess Peach, Donkey Kong, Bowser, and Wario joining Mario as infants.
