Step-by-Step Guide

1. Place the floating wooden platform in the center of the room, ensuring the longer edge is flush with the bottom wall and the shorter edge aligns with the right-hand wall. Ensure no part of the platform floats above the water or exceeds room boundaries.
2. Position the central sushi bar with the blue-tiled roof in the back-left corner. Align it flush with the left and right interior walls, ensuring the roof peak is slightly below the top edge of the walls.
3. Add the airplane-shaped fish tank on the roof ridge, two-thirds towards the back corner. Fill it with miniature tropical fish and coral, ensuring balanced visibility.
4. Install the sushi bar counter with the curved, white-trimmed piece at the front edge of the building. Then, place the transparent fish display tank on the right end of the counter, ensuring proper alignment.
5. Furnish the area with curved wooden benches, small backless stools, and life ring cushions in front of the sushi bar counter. Align appropriately to avoid overlaps.
6. Hang soft purple lanterns evenly along the roof’s overhang and arrange seaweed patches and decorative shells on the roof and walls. Ensure alignment with valid points to avoid floating artifacts.
7. Install the cat chef signpost at the front-left corner of the platform; place a small wooden rowboat on the adjacent water with oars angled diagonally.
8. Arrange the fish drying rack, fishing net, bucket, and rod on the right side near the back-right corner, maintaining a natural appearance.
9. Arrange food display items and ingredient baskets on the counter in a visually pleasing fan pattern, ensuring no overlap occurs.
10. Place cat characters around the sushi bar and fishing area to bring the scene to life. Position them in their designated roles to enhance the immersive atmosphere.
