WHAM! "What the?! Does that chest have arms?" SLAM! BAM! POW!
A step away from the traditional "mouthy" mimic. I saw a post on Tumblr where someone suggested a mimic who punches instead of bites, leading to the terrific art above being created. I tried to be as true to the image as possible. This would make a unique encounter for your players and foster a distrust treasure chests for years to come.
Thank you for taking the time to view my make. If you print this model, please share an image for posterity.
All fear the Dungeon Master, long may he reign!
