not hard at all
Go into the rat, change its ObjectID, attach a script that sets its acal to however you want ( 0.2? ), make it sommonable (checkbox), and creat a spell that lets you summon him.

You would have to retexture him, if you know how,, it wont be hard tho, you just gota highlight everything, and make him Greener (that a word?)
if you realy want to go all the way and learn to texture, its a bit difficult at first but after you play with it for a wile it gets easier.
