Hitting a Rolling Cactus with a Wooden Sword to make it roll.

The Rolling Cactus is a placeable object that behaves similarly to the Boulder. It is stationary when placed, and begins to move when hit by projectiles, pickaxes, or drills, or when the blocks under it are mined or hammered. Its roll direction is determined by whether its horizontal position in the world is an odd or even number, regardless of the slope of the surface it is on (unless it is blocked on one side by blocks, in which case it rolls in the other direction).

When both blocks under a Rolling Cactus are removed or hammered into a half-block, it will drop vertically until it hits a surface, then bounce and roll.

A Rolling Cactus projectile pierces an unlimited number of entities. When a Rolling Cactus that has already started rolling falls onto a lower surface, it maintains its forward momentum while bouncing back up, releasing 2–4 Rolling Cactus Spikes that travel in random directions. Hitting a vertical obstacle also releases Spikes, but destroys the Rolling Cactus. A Rolling Cactus' movement is affected by liquids, and it can roll uphill.

A stationary Rolling Cactus deals 21–29 damage when a player touches it.[1] A Rolling Cactus projectile deals 76–104 / 152–280 / 228–312 or !!Error: Invalid EICONS input! 120–160 / 240–320 / 360–480 damage to players ( 38–52 / !!Error: Invalid EICONS input! 60–80 damage to NPCs, enemies, and critters) and deals a knockback of 10 (Extremely strong) on contact.[2] Each Rolling Cactus Spike deals 51–69 / 102–138 / 153–207 or !!Error: Invalid EICONS input! 34–46 / 68–92 / 102–138 damage to players ( 26–34 / !!Error: Invalid EICONS input! 17–23 damage to NPCs, enemies, and critters), deals a knockback of 2 (Very weak), pierces entities, and breaks on contact with blocks.[3]

  • A Rolling Cactus cannot be retrieved once placed, as hitting it with a pickaxe or drill, which would otherwise break the tile and drop an item, causes it to start rolling.
  • Similarly to the Boulder, the Rolling Cactus accelerates to a top speed of 36 mph over the course of 2.18 seconds.[3]
  • Once rolling, a Rolling Cactus always causes the same amount of damage, regardless of its speed. A player or enemy hit by a Rolling Cactus that just began rolling will take just as much damage as they would from a fast-moving Rolling Cactus.
  • Like all other projectiles, the Rolling Cactus will break after rolling for one minute. It will not release Rolling Cactus Spikes in this case.
    • If moving along a flat strip of land, it can reach a maximum distance of 1559 tiles.
  • If a Rolling Cactus hits another Rolling Cactus, it will cause it to start moving, but will break upon the impact (unless both were placed adjacent to each other).


  • The tooltip is a reference to the opening lyrics of the song Ridin' by American rapper Chamillionaire, "They see me rollin', they hatin'..."
  • Once the Rolling Cactus has reached top speed, it completes a full rotation approximately once every quarter of a second.


  • Desktop 1.4.2: Fixed a recurring issue with Rolling Cacti spawning on Altars and causing crashes.
  • Desktop 1.4.1:
    • Reduced the base Rolling Cactus projectile damage from 70 to 45.
    • Increased the base Cactus Thorn projectile damage from 20 to 30.
