NPC Creature to Baby Murloc?

[Warcrown]

I was wondering if it is possible to change a common creature species that appears in numerous regions into baby murlocs, and if so, how would I go about doing this? (all of this would be on a live server)

**Example**
Snowshoe Rabbit > Green Baby Murloc
Brown Rabbit > White Baby Murloc

I suggest you get MyWarcraftStudio and read some tutorials, it shouldn't be too hard to do :3

I am so brand spankin' new to this whole thing. I think I've done the "mini-patch" correctly but have no clue how to get to the whole part where I use wowme. I'm confused. lol

EDIT: Nevermind. I figured out what one simple thing had to be done, and I think I might need to look into figuring out what sound to use so I don't have a baby murloc making the rabbit death noise when killed.
