Blooey is a character that appears in Paper Mario: The Thousand-Year Door. He is one of Luigi's partners that joins him on his separate journey for the Marvelous Compass. He and Luigi went onto a journey to Rumblebump Volcano but things went a little wrong and Blooey got into an accident.
Blooey is a brown Blooper. He was originally white but Luigi accidentally threw him into a volcano when they were battling a stone creature causing Blooey to turn a golden brown.
Blooey is shown to be full of anger after Luigi basically made him "edible." Blooey stated that the only reason why he is going with Luigi on his journey is to, one day, pay him back for burning him. He even states that he'll get back at Luigi even it takes him his entire life.
