Daddy Bear is an NPC in City of Academia AF4XXX who will reward you with 5 fragments if you answer his questions correctly. He will ask questions about FF13-2, FF13 and general Final Fantasy questions during his quiz.
You will need Moogle Hunt to detect him. Though you have unlimited tries but once you give an answer, be it right or wrong, he will vanish and spawn randomly on the different locations throughout the map.
Questions he asks are limited so they will repeat after few tries which makes it easier to answer correctly as you play more of his quiz.
Finding him is annoying but you do need fragments right ? so refer to the map with pin-point locations where he usually spawns:
If you find any location missing on the map, pin-point it on the map and let us know.
