Joke[]
The melody has been changed to "Gadget Room". At 0:58 the melody changes to "We Are Number One" and at 1:24 the melody briefly changes to "The Lick". At 1:30 the melody changes to the "Ruins" leitmotif from Undertale. At 1:45, the melody changes to the "Snowy" leitmotif also from that game. At 2:31, "MEGALOVANIA" briefly plays before eventually fading out.
