|The four possible sandcastle variants.|
The Sandcastle Bucket is a tool that places a decorative sandcastle and consumes one Sand Block upon use. It can be used on all variants of Sand Blocks and platforms, in any biome. Sandcastles are background furniture objects, but they cannot be picked up; using a pickaxe or drill on them destroys them immediately.
When the cursor is moved over a valid block, one out of four sandcastle styles will be selected randomly. Moving the cursor over a different block will produce a different sandcastle preview, so players can choose the particular sandcastle variant they wish to place by moving their cursor back and forth.
- The spiral-styled sandcastle is a reference to the World 5-Spiral Tower level from the platform video game Super Mario Bros. 3.
