Chocolate Banana (Incongruent) (1223)

Divide the grid along the dotted grid lines into regions. Each region must either be "chocolate" (in the shape of a rectangle or square), or "banana" (not in the shape of a rectangle nor square). No two "chocolate" regions may share an edge, and no two "banana" regions may share an edge. Each given number indicates the area of the region that number is in. (It is possible for a regions to contain no numbers, or to contain multiple numbers.)
Except for regions that have only one cell, no two regions may have the same shape. (Rotations and reflections of a region are considered the same shape.)
