Basically, baby Gagas are carnivores that receive food from their parents or older sisters, but this one was kept by humans and will ask for a baby bottle (or food/drink) like a baby. It says "Pao Pao" every time it does so (however, this one was abandoned and has no owner). It does not say it under normal circumstances. Only when it is hungry or thirsty.
