Grander Box

What are Grander Boxes?
Like Grand Boxes, Grander Boxes are required to beat in order to access the next dimension and are locked until you beat every other box in their Dimension. However they are only seen in Super Dimensions, they are also longer than any other Grand Box and are the finale of the whole stage of dimensions that they are in.
