didn't know where else to post..But whats the deal with "Frieghtened Rollerrats"?

Started a new character lastnight...exploding chests(lots of)locked doors(on the 1st mission in training)and a useless pet....

I've had (on 3 different occasions)have "freightened rollerrat" hop out of chests(even explod'n ones).

Couldn't control them(other than "location").couldn't attack'em(since they were "my" pets).They wouldn't even follow me......

.....A waste of code?.....

Probably not finished, whatever they had envisioned when they did it. Either it is supposed to attack us or be our pet for the mission, and either way works fine by me.
