I (alliance) never received this quest or it's precursor Back in the Saddle. Instead, after the turtle mount quest I immediately got the seahorse quest.

Description
<Erunak speaks as he places the turtle meat into a porous sack.> Ready yourself, {name}. There's no telling how this might end up, but we don't have much choice if we are to rescue your friends. Take this sack and use it at the sunken anchor southeast of here. Once you've attracted a shark, do your best to ride it back to me here. If you can do that, you will have a most intimidating means of transportation.
