The 沙灘球 is a novelty item. Using it creates an interactive beach ball for players to bounce around. After 2 seconds of sitting still, it turns back into a dropped item that can be picked up and reused.

- On the 主機版s , 移動版s , and the it cannot be purchased, and can instead be found in Water Chests. 版
If the Beach Ball is 'hit' more than 10 times without it touching the ground, a status message appears saying 'Beach Ball was hit X times before hitting the ground.'
- The Beach Ball reacts to 物塊s, 門s, and 液體 as boundaries and will bounce off them normally.
- When touching players, the ball reacts as though it were struck, repelling away with increased velocity. This occurs even for players standing still, but more so if they are in motion, which can easily send the ball flying off-screen.
- The Beach Ball is not affected by NPCs or 家具, and 武器s or 工具s used on them will simply pass through without interacting.
- If the Beach Ball travels off the left or right edges of the map, it often cannot be retrieved, and presumably despawns.
- The Beach Ball is considered a projectile, and will therefore activate 青綠壓力墊板s.
