At the start, "Crank That" is mashed up with the advertised track, with the steel drum playing to the melody. At 0:22, the vocals from "dat boi!!!!" by ZimoNitrome are added to the rip, with the Daniel (UK) from ttsdemo.com text-to-speech voice at 0:45, singing an extra verse, based on the first verse of "Crank That":
I'm rolling on you, rolling on you
And when we get online
Then I'm trolling on you, trolling on you
Catch me at your local party
Yes I'm memeing everyday
Normies getting mad cuz
I got my dick out for Harambe
At 1:18, the vocals switch to "Crank Dat Hentai Boy niggGAAAAA" by HENTAI DUDE.
The use of "Crank That" likely references to the rips "Super Mario All Stars SMB3 Enemy Battle", "Hammer Bros. Theme - Super Mario Bros. 3", and "Hammer Bros. Battle - Super Mario All-Stars: 25th Anniversary Edition", which were all mashups with the original "Crank That".
