Shapes is the 17th level of Bloons.
This level is very easy to complete as all you have to do is shoot the groups of Tack Bloons of each shape which will result in popping all of the regular bloons surrounding it.
- The level can be beaten using only 2 darts: the first one must pop 3 shapes, the second one must pop the remaining 2 shapes.
- The level consists of five 'shapes', hence the name. These shapes include a diamond, a triangle, two rectangles and a square with its corners removed (or circle).
