Hi, Now I'm going to show you how to create custom mount
I don't know if it was posted before, but:
1. go to wowhead.com and find any mount, we will use Argent Hypp (you need find spell!)
2. look at Effect #1 Apply Aura: Mounted (33857)
3. go to creature_names and find creature with entry 33857(apply aura), now change male_displayID and male_displayID2 to display ID of your new mount, we will use 23345 (Kalecgos)
4. save everything and reload creature_names or restart server
wohoo! you have custom mount!

I hope it helped
P.S.: My english is bad :-X
