I am confused here. What exactly are you trying to say? You said a rubix cube can break tank glass? ... well im not so sure about that.. maybe if the rubix cube was shot through a cannon or a gun then that would make sense....
im sure i saw that episode but i dont remember a mantis shrimp doing that.i did see it break glass tho.how can it even turn a rubic cube...i cant even solve a rubic cube.............
