Once you open it, it's probably going 
to be a man-eating mimic or something.
Wenn du versuchst sie zu öffnen, 
verwandelt sie sich in ein Monster oder so.
Probablemente cuando lo abramos 
será un Mimic come-personas o algo así.

sale un Mimic come personas.
Il doit y avoir un monstre
à l’intérieur.
Quando você abrir, deve dar de cara com
um Mimic comedor de homens ou algo assim...
