that is part of it, it starts off

stamp op de grond
jump jump jump jump (pronounced more like “jomp”)
draai maar in het rond
spring maar in het rond

then indeed the “derp derp derp” before

spring maar in het rond

those Dutch lyrics are also part of a childrens song for playground games…

the rest of it I can understand but am not 100% sure of the exact lyrics, though its near enough a direct translation of the English version. TBH his other track “Hoogtevrees” (parody of Lady Gaga, poker face) is better(though you need to know some Dutch to get the joke)
