This guide explains a neat conical roof that works with the limited parts selection in purple.
The base is made of this purple element, while the reddish brown pieces simply show one method for attaching the roof.
The second layer is made of a travis brick and assemblies of 1×2 plates, 1×1 round plates, and 1×2 curved slopes.
1×2 tiles with hands on the bottom will then fit into the spaces between the curved slopes.
The ‘wrist’ section of the hands goes on top, and a blue rubber band holds these elements in place. It may take a few tries to get everything to stay in place properly.
Though once you’re able to fit the two sections together it’s quite stable.
Last is a 2×2 cone which finishes the roof.
The roof fits very well over a 4×4 round structure.
