I found this interresting article about PuPu, at Ign.com
UFO?
Aegis Amulet
Accelerator OR PuPu Card
If you've been an avid reader of Occult Fan Magazine you've probably heard about the mysterious Unidentified Flying Object. You may already be a believer if you've had any close encounters of your own during your travels. Whether you have an appetite for the unexplained or just an appetite for rare items solving this mystery should prove worth your while. Begin by tracking the UFO in each of the following four locations in any order:
Mandy Beach: Travel to Timber and explore the beach east of the city. You'll spot the UFO abducting a moai statue.
Winhill Bluffs: Travel to Winhill in the southern region of the Galbadia continent and explore the area southeast of the village and west of the rocky path where Winhill Bluffs meets Lallapalooza Canyon. You'll spot the UFO abducting a cow.
Kashkabald Desert: Travel to Kashkabald Desert in southern Esthar and explore the western part of the desert. You'll spot the UFO abducting a pyramid.
Heath Peninsula: Travel to Heath Peninsula in eastern Trabia and explore the small island east of the peninsula. You'll spot the UFO abducting a crop circle.
After you've made all four sightings pilot the Ragnarok to Grandidi Forest in northern Esthar and set down on the highlands just north of Chocobo's Holy Forest. Explore the area and you'll encounter the UFO up close. Unfortunately you must destroy that which you do not understand. Any attack will do, the UFO won't fight back, but you may want to take the opportunity to stock up on Demi first. When the damage is done the crippled craft will fly off and crash in the distance. You'll be rewarded for your heroism with an AEGIS AMULET.
If you're still curious about the extra-terrestrial visitor you'll have to travel to Balamb to find it. Explore the area near the crater where Balamb Garden used to rest and you'll encounter PuPu. There are two ways to deal with the creature: if you're bona fide blood-thirsty you can butcher the defenseless and decidedly cute little alien for an ACCELERATOR. If atonement is on your mind you may recall from reading Occult Fan IV the UFO was searching for Status Full Recovery Medicine. To offer amends make sure you have the Item ability junctioned to at least one member of your party and five Elixirs in your inventory before you engage PuPu. At the beginning of the battle the alien will ask for Elixir. Grant PuPu's request and the doe-eyed Oliver Twist will ask for more. Continue giving the creature Elixir and, when adequate health care has been delivered, PuPu will thank you by giving you the PUPU CARD. In either scenario you may want to take the opportunity to stock up on magic before administering PuPu's fate.
