ah, i remember those days, my crab did that too. he even would attempt to do lotr reenactions on "his lr" he was a thief he stole from my sfes all the time.
I've had him for about a week and he's stayed pretty inconspicuous, must have been practicing up for the big show last night. The little guy did all that with a missing leg too, didn't notice it before because he had been a bit shy.
