Collecting all of the 30 Chinpokomon will reward you with a friend request from the Chinpokomon Corporation. Which is needed for the "More Popular than John Lennon" Trophy / Achievement. On your way you will also unlock "Poco Chinpoko" (5) and "Chinpoko Loco" (15). Some of the Chinpokomon can only be collected during specific Quests and can easily be missed. Once a Quest is completed, you can NOT go back.
