Blooey is the first partner Luigi met on the Pudding Continent on his journey through the Waffle Kingdom. After several days fording through the jungle, he encountered Blooey in a remote town. Blooey was on a journey of his own at the time, but he joined Luigi after hearing his quest.
He was known as the "White Torpedo" in his hometown, presumably due to his speed and (formerly) white color.
Inside of Rumblebump Volcano, he and Luigi encountered a 100-foot tall statue, whose weak point was a red gem on its forehead. Being far out of the range of Luigi's jump, he hurled Blooey at the gem in an attempt to defeat it, only to trip and fry Blooey in the lava, resulting in his crispy, lightly browned appearance.
Blooey harbors some clear resentment towards Luigi for his costly mistake which resulted in the browning of his formerly pale skin. He claims to follow Luigi on his journey only to make him pay for what he did. Upon completion of Chapter 7, Blooey appears by Luigi again in the inn, where he is even more burned. However, this time he has forgiven Luigi and reveals himself to be relieved.
