I remember the time who my Loomi would run through a wall, and a Thunder Snake was lightning it at the same time, and it continue to run, and run...
Thunder Snake is fun, but they need a real protection, because they don't have a good amount of HP :(
@xxkeegiexx : Like I explain that, each player has a pet who is the strongest for him. You must find the pet you prefer, and level him till he content you. But, yes, for me, it the FireStarter.
