This extraordinary sea creature can be made out of 8 to 11 basic Lego Duplo bricks, considering the use of 2×4 instead of 2×2 bricks – I did it twice this time, bause of the lack of 2×2 brown bricks. In this exact replication you can see a 9 brick version.

I opted for genuine colors, including yellow bottom.
