Harrison is a character featured within The Minish Cap. He is a young boy that attends Funday School. Link is first able to meet Harrison after completing the Temple of Droplets, in which Link can then enter Funday School. While at school, Harrison eats his lunch as fast as he can to assure that he can have a longer recess.
Link is able to fuse Green Kinstones at various points in the game with Harrison. As it is a Green Kinstone fusion, it is not set to a specific treasure chest, but instead, one of the many possible treasure chests. There is one random Red Kinstone within the game that opens up a location in the Hyrule Castle Garden leading to a Piece of Heart, as well as a random Blue Kinstone that opens up a tree in North Hyrule Field leading to a Fairy Fountain. Harrison is one of the many characters in which Link can make these Kinstone fusions with.
Harrison's sprite image is identical to Erik, another one of the students at Funday School. It is possible that the two are identical twins.
