What is the creepy-looking 
ball of energy next to you?
ما كُرة الطاقة المُخيفة تِلك التي تُجاورك؟
Und was ist das für ein hässlicher
Energieklumpen neben dir?
¿Qué es esa bola de energía repugnante?
¿Qué es esa bola de energía repugnante?
Et c’est quoi,
cette boule d’énergie dégoûtante ?
E quell'inquietante palletta d'energia 
che ti fluttua vicino chi è?
O que é essa bola de energia 
esquisita do seu lado?!
Что за мерзкий сгусток энергии
рядом с тобой?
