Papi is a female harpy of unknown age. She's joyous, absent-minded, and a bit naive. She can be a little air-headed at times, has a short-term memory, as well as a short attention span. She doesn't understand human norms and has no concept of modesty, but it's not a bad thing. She's actually surprisingly motherly, and is very good with children, but she does act childish herself all the time. Despite Papi's childish demeanor and appearance, she gets angry when called that, and gets defensive.
