SpongeBozz is a comic alter ego of popular German rapper Sun Diego, in which he dresses up as cartoon character SpongeBob Squarepants and performs aggressive battle raps. The character first appeared in 2013 as a competitor on German online battle rap competition JuliensBlogBattle. SpongeBozz won the competition, beating out rapper 4tune, and returned the following year, winning again with an elaborate video diss against rapper Gio. SpongeBozz's identity has been officially kept secret, but several listeners pointed out similarities between SpongeBozz's rapping style and Sun Diego's, and Sun Diego collaborator Kollegah confirmed the identity in an interview with German hip-hop magazine Juice. SpongeBozz announced his retirement from the battle rap scene with the announcement of debut full-length Planktonweed Tape. The album appeared in April of 2015, and immediately hit number one in Germany and Austria. His follow-up, Started from the Bottom/KrabbenKoke Tape, arrived in 2017 on the indie label Bikini Bottom Mafia/Soulfood. ~ Paul Simpson, Rovi
