Creating a large whirlwind 
with its massive size,
تصنع زوبعةً كبيرة بحجمها الهائل
Mit seiner gewaltigen Masse
einen riesigen Strudel schaffend,
Crea un enorme torbellino
Crea un enorme torbellino
Un gigantesque tourbillon
forme une tornade d’eau
Grazie alla sua corporatura massiccia 
crea un grosso vortice
Isso cria um turbilhão de tamanho gigante...
