Box Stack of Twisted Terror

What is the Box Stack of Twisted Terror?
The Box Stack of Twisted Terror is a (???) difficulty box stack. This is the only box stack in Area 1, so you might want to move on to Area 2 if you want to play more box stacks. The frame of this box stack is twisted, which adds that word in the name.
