I have been preparing an adventure for a 5-6 level adventuring party in the Pathfinder System (not done yet).
It's with Goblins. And since Goblins are born riders (+4 racial bonus to ride checks) I gave them a mount. It's a rabbit. A dire rabbit.
Drawn during an 8 hour long schooling session at work. It wasn't an uninteresting schooling mind you. I just have to keep my hands occupied somehow.

The one on the right is the mount of the leader of the Rabbit Riders. A female goblin specialized on mounted archery wielding a special bow. Her father is the clan leader and rides the more traditional Worg (for Goblins at least).

Special Mount abilities are the high jump and the ability to perform the run or the charge action with a 90° turn.
