Easy as Coral

Paint some cells black to form a coral - single connected area. No 2x2 squares can be completely blackened. The coral doesn't have any holes - all white cells should be connected to the edge of the grid. Numbers outside show the lengths of the first fragment of the coral in the corresponding row or column.

Example puzzle

Grid control: Click the mouse button at the selected cell to change the color of the cell. Second click will put auxiliary cross sign, which doesn't affect correctness of the solution, but helps visually. You can also drag the content of one cell to another with the mouse. More details about grid control are at the help page.
