Trivia

 * The music used in Gooper Blooper's battle is a remix of Boss Battle from Super Mario Sunshine. This remix is from Mario & Sonic at 2012 London Olympic Games.
 * This music used to be shared with King Bob-omb and Petey Piranha in Demo 3, making it the only main boss theme that was used by multiple bosses.

Lore:
Gooper Blooper is the largest of the Blooper species, a species that is observed to mainly dwell in underwater areas, and some spotted swimming in the air. But there came one time when Bloopers were massive, and these times aim to prehistoric times, where Bloopers were much larger, and were more menacing. Gooper Blooper seems to be one of last surviving prehistoric creatures, that slowly diversed into the smaller Bloopers we know today. But how did this creature survive for so many years without going through immense changes? Some say he was frozen in ice and preserved in the depths for many years... Some say Gooper Blooper isn't deriving to the prehistoric times... Whatever it is, this creature's presence gives terror to many sea critters.
