How to unlock the Clutchgod Achievement for Going Under

How to unlock the Clutchgod Achievement

To get the Clutchgod secret achievement you must kill a Hungry Box which is a mimic cube. Essentially what you are looking for is a CPU cube that barks at you and chases you around. A Hungry Box looks like a normal cube but when you get close it will start attacking. The mimic cubes do not start spawning until the second half of the game when you have completed four dungeons and they are reset for story reasons. You will be able to find a Hungry Box mimic cube within the first floor in Joblin after the mid-point of the game.
