Faster! Move like you're being chased by a demon!
!أسرعوا! تحرّكوا وكأنّ شيطانًا يطاردكم
Schneller! Stellt euch vor,

¡Más rápido! ¡Corran como si un demonio
viniera detrás por sus vidas!
¡Más rápido!
¡Como si os persiguiera un demonio!
Plus vite ! Imaginez
que des démons vous poursuivent !
Più veloci!
Mais rápido! Andem como se estivessem 
sendo perseguidos por um demônio!
Шевелите ногами!
Представьте, что по пятам спешит демон!
ขยับขาให้เร็วกว่านี้!
