From Pikipedia, the Pikmin wiki
The Taste Sensation (ふるさとの味?, lit.: "Home Taste") is a treasure found in Pikmin 2. Although often mistaken to be sushi, is actually a onigiri, or Japanese rice ball. It is found on Sublevel 2 of the Snagret Hole and is randomly located somewhere in the open field. Many enemies may hinder this treasure's journey to the Ship.
“Some things on this world can't be understood, no matter how much I analyze them. For instance, this is the first time I've tasted this, yet it has a nostalgic taste. It's inexplicable! It tastes like something my mom has made for me by hand.”
“In this modern world of artificial foods, all things taste the same, despite your dear tongue buds. If that describes you, then this is for you. Its flavor is the balm to heal your wounded soul!”
