As a player who has decided not to subscribe because I didn't feel the game was yet worth it... the 'bribe mount' is indeed trying to cast its spell on me. I think it's hilarious, and I might convince myself to pay $9.99 for it (by subbing for a month), considering a sparkle pony and other cash shop mounts in WoW could cost me up to $25...
If you were planning to try out 1.21 you could just wait until then, since the Goobbue will be available until 2.0.
