Panda, part of generation cupcake, is prodded by his mother to get a job, but he just wants to eat bamboo. While avoiding his mother's ire he happens upon a cafe run by Polar Bear, who just so happens to be looking for a part-time employee.
I guess that's "acting naturally" to him.
Esa es la naturaleza de 
Panda. Definitivamente.
Supongo que para él 
"actuar natural" es eso.
C’est donc ça,
 son état naturel.
Parece que é assim que ele age naturalmente.
