Marsh/Row 6

Design: This row is the last one to make use of the rotatable polyominoes. It has an orange background that matches the vegetation behind it, but can also be seen as a mix between the red background of Row 3 and the yellowish green background of rows 1, 2, 4 and 5. The reason is that you have the choice to see these puzzles as following the logic of the puzzles of Row 3 with a red background, or to follow the logic of the other puzzles with yellowish green backgrounds, or mix the two logics. Half of the puzzles use holes in the grid to prevent you from placing the polyominoes in the most obvious position (as in rows 1, 2, and 5), but the other half uses polyominoes with unusual shapes as in Row 4 for that purpose. The consequence is that you can either try to make paths connecting the cells containing polyominoes, as in Row 3, or you can first try to combine the polyominoes before placing them in the grid as in row 4. So in the end, that row is a kind of conclusion, summarizing all the puzzles seen until that point in the marsh. And we have this conclusion because after that we will enter a new part of the area with the underwater rooms and blue-outline polyominoes.

Relation with other puzzles: The last puzzle of the row is reminiscent of the puzzle of the second moving platform, by the disposition of the cells containing polyominoes, and by the shape of the bottom one.
