Jimmy Buffett is the most iconic figure I can think of associated with Florida, even though he's actually a Mississippi Democrat.
His song "Fins" is about being encircled by sharks.
Trump should mock DeSantis with this song, because "the big white teeth" of "the sharks that can swim on the land" are absolutely devouring him right now and he's effectively surrounded and sunk by a much stronger predator.
Moreover, and more importantly, the song is incredibly catchy and easily sung by a crowd. It's the perfect song to both intimidate DeSantis and rile up the fans.
Hey Donald, if you go with my suggestion, call me, OK? This could be the beginning of a beautiful friendship...
