Okay, we all know the tame rat is one of the most important sources of trauma in the whole game. Either it dies against the boss (he is too awesome to lose against underlings), either you go away and he watches you climb down the stair, tears leaking in his "beady eyes", sitting here, waiting for your return, starving, or even worse, you can shoo him away, "breaking his little rodent heart".
No!
Tame Rat should become a recruitable Npc! With evolution, skills, and his incredible model dripping with sheer awesomeness! Think of it: a cute rat following you everywhere... (and if he got more lines it would be... *faints*)
