I fought Chok Ak'Ab in the Pyramid of Fire over and over again both in Test Realm and now in Live and all I seem to get from him is ONE pet snack and nothing else. I reported this using the in-game bug reporting in Test Realm, but nothing has changed. Both of the other bosses have dropped special jewelery and something else consistently, but not the dino. Just pet snacks. Every time. Without fail. One pet snack.
