Walker

Congrats to @Malrog, @Shogia, and @Cow for guessing today's genre correctly and earning a bonus otter! 🦦

Today’s GAPP is a Supersized Penta Touch (also known as Touching Pentominoes)! We got a large shipment of L pentominoes at the warehouse and need to use them up somehow 😅

Rules: Place each pentomino from the bank given outside the grid into the grid so that no pentominoes touch one another orthogonally. Rotating and reflecting pentominoes is allowed. Every grid point on which two pentominoes touch diagonally is marked with a dot.

Note: Pay careful notice to the "negative constraint" - two pentominoes can only touch where there is a dot! E.g. for the example, this is what makes the placement of the O tetromino unique.
