The upcoming TCG booster release, Throne of the Tides (Cryptozoic, October 2011) will reportedly feature some ultra-cool loot cards, including a mind-blowing mount and possibly the cutest wet pet of all time! I nabbed this paragraph from a card distributor's website:
The three new loot cards for this set are good ones. The epic is the Tallstrider Mount. This is a unique mount not available in the MMO currently. The rare is Throwing Star Fish which players can throw at one another, and it will “stick” in them, which will be fun. The common is Fish in a Bubble which is a cosmetic pet puffer fish in a bubble.
I haven't seen any datamined images of either pet or mount yet, but I'm confident the always awesome Blizz CG artists will not disappoint! There's just one problem. It's not October yet! Hopefully I can get my hands on a Throne of Tides loot card or two to give away! Stay tuned!
