The Super Happy Tree as it appears in Yoshi's Story
The Super Happy Tree (sometimes known as the Marvelous Tree of Mirth)[1][2] is a tree that is found only on Yoshi's Island in Yoshi's Story. It grows every type of fruit available on the island, including the magical Heart Fruit. It is the ultimate source of all the Yoshis' happiness on Yoshi's Island. Baby Bowser steals the Super Happy Tree for its power, but the Baby Yoshis later reclaim it. Baby Bowser later claims that it tasted rotten to him anyway.
In the Yoshi's Story manga adaptation section of Mario no Bōken Land, the Super Happy Tree makes an appearance.
