The trick
No inside walls needed: the four floor tiles clip to each other down the middle, and every rim wall grabs the floor edge under it plus its neighbour at the corner, so the wide mouth holds its shape on its own.
What you will need
- 12 square tiles
Step by step
1. Lay the wide floor
Push four blue squares together into one big two by two square for the water.
2. Wall the front and back
Stand two green squares up along the front edge and two more along the back edge.
3. Wall the two sides
Stand two green squares up each side to close the box, pressing each one into the corner so it grabs the front or back wall.
