Since the last patch we have found FROG and SCARAB / both of which are new pets that are dropped in the game as part of the treasure we get. My ? is be there others that we should be searching for / and maybe a wee hint as to which world to be looking in if there are.
Check out Pirate101 Central's First Generation Pets and Pirate101 Central's Hybrid Pets for that information. It tells how other people have obtained the Pet and, usually, what world the Pet is from and what food it will love when that food comes from that world. There is also information about what Talents and Powers that Pet could have. Of course, someone has to post this information first. The newly discovered Hybrids and First Generation Pets will have very little information. Maybe you could be the first to post it!
