Huh? But teasing my master is what I live for!
Wie? Dabei lebe ich doch dafür,
meine Meisterin aufzuziehen!
¿Eh? ¡Pero vivo por molestar a mi maestra!
¿Eh? ¡Pero si vivo para
 molestar a mi maestra!
Eh? Ma tormentare il mio Master 
è lo scopo della mia vita!
Hein? Mas eu vivo para 
atentar a minha Mestra!
