Blossoming Ancient is a Battle Pet, not a Mount, tho clicking on the link would tell anyone that. Still, it would be nice to see the post updated so as not to confuse anyone into thinking there is a second tree mount available somewhere.
Nice! New form for my favorite tree mount to run around on while I quest :)
Wandering Ancient is the correct link for the mount.
The change of foliage on the wandering ancient mount is a nice little touch (even though to an Australian player the seasons are back to front), it's a nice reminder of the ponderous passage of time. I thought the trigger date for the change was the solstice, a few days ago, to be honest.
Te mount foliage should just come off and have naked branches as is the winter custom among trees. :)
