Thought my players were going to give up on the 'taming of the mimic idea'. They weren't looking forward to footing the bill for it's eating habits. But such as players do sometimes, they found a very creative solution...
They gave it the clear spindel ioun stone (you know, the stone that makes it so you don't have to eat or drink) found in Jzadirune's bathroom.
And since half the group speaks gnomish, they also now have 2 pulverizer automatons (formerly damaged, healed thanks to the groups Artificer), hard at work making the group a new basement..
But they're happy
