Panda has convinced Polar Bear and Penguin to visit him at the zoo.  Being their first time, Polar Bear seems to want to go places he is strictly forbidden.  Back at the Café, the zoo workers discuss the pains of stereotypes.
I think the act of acting 
naturally is "acting natural."
Estar en forma natural, es lo natural ¿no?
Comportarse de forma natural 
es actuar con naturalidad.
Être dans son état naturel,
Acho que agir naturalmente é ser como 
se estivesse em seu habitat natural.
