As a gift for Hell's celebratory party, God orders the designers to come up with
"an animal that can be used in Hell's attraction and also sent to Earth".

This system is more efficient than 
just breathing with the lung.
لهذا الجهاز فعاليّة أكبر 
من مجرّد التنفّس بالرئة
Dieses System ist effizienter
als nur mit der Lunge zu atmen.
C’est plus efficace que
si le poumon devait se débrouiller.
È un sistema più efficace della semplice
respirazione fatta usando solo il polmone.
É um sistema mais eficiente
do que respirar só com os pulmões.
Это эффективнее,
чем дышать только лёгкими.
