Step-by-Step Guide

1. Prepare the Water Border and Grassy Foundation:
   1. Select the pale sky-blue frame tile from your décor menu and align its rounded lip along the bottom edge of the placement grid to form a continuous water channel.
   2. Choose the large irregular green turf piece and fit it into the left section of the blue frame without overlapping the water moat. Ensure no gaps or misalignments.
2. Construct the Pillared Platforms:
   1. Locate the tallest light-gray column and secure it onto the grass foundation at the center-rear.
   2. Attach the medium-height cylinder to the right of the tallest column, maintaining a single grid square clearance.
   3. Position the shortest cylinder in the far right corner, aligning it with grid lines.
   4. Add the petite cuboid block to the front of the medium column for a staircase effect.
3. Position the Blue Shell House and Interior Accents:
   1. Install the whimsical cerulean shell-like dwelling on the green turf, slightly right of the center axis, with its open face forward.
   2. Inside, place the semicircular wooden balcony rail at the front, set the miniature desk behind it, and insert the curved sleeping alcove piece beneath the balcony.
4. Assemble the Tree Trunk, Leaf Platforms, and Blooming Vines:
   1. Connect the sculpted brown trunk segment to the top of the tallest column.
   2. Perch three cube-shaped foliage blocks atop the trunk’s branches, ensuring level alignment.
   3. Clip the sinuous green vine pieces around the trunk, weaving white flower tendrils between the leaf platforms.
5. Add Bird Companions, Nest Elements, Flora, and Ground-Level Details:
   1. Place the pastel-blue bird figurine on the leftmost foliage cube and the pastel-pink bird on the right, angling inward.
   2. Set the tiny nest with three white eggs on the center cube.
   3. Tuck a small palm-leaf cluster behind the blue shell house and a broad four-leaf component to the left of the grassy mat.
   4. Arrange oversized mushrooms near the right cylinder, line up stump stools in front of the shell dwelling, suspend the cauldron from its wooden support, and bridge the water channel with a walkway.
   5. Dot the water border with lily pads and position the tiny frog figure on one.
