Gobblegut is a boss from Super Mario Galaxy 2. He is a green dragon, with red balls in between his body. Mario can smash these to harm Gobblegut.
Gobblegut resembles a giant serpentine dragon with a row of numerous Bellyache Bulges (large pink swellings) growing from its body. Its scales have swirl designs, though its underside lacks scales, thus exposing its pink skin. Gobblegut has a few jagged crystals protruding from its head, and it has a large bulbous chin that has numerous scars on it (most likely due to the numerous times it slams his chin into solid rock). It also has orange eyes with a demented look to them.
