Crate Shower is when crates start appearing randomly on the landscape during a turn. The crates contain completely random weapons and utilities - the Crate Probability settings do not affect what appears. Anything from Bazooka and Grenade, to Super Banana Bomb and Armageddon, and even Skip Go and Surrender can show up in weapon crates, and anything from Jet Pack to Double Damage and even another Crate Shower can show up in utility crates. Health crates can also appear, but are mostly common in the 3D series.
Certain utility crates will contain Crate Shower. When a crate with Crate Shower is collected by a worm, crates will start appearing immediately. The Crate Shower will last only during the turn in which it is collected (except if it is collected during retreat time, it will take effect during the player's next turn). In addition, certain Wormpot modes such as "Crates, crates, and even more crates", or "No weapons, crates only" will trigger automatic Crate Showers each turn.
- In the 2nd generation games, Crate Shower appeared as a selectable utility. In later games, it was changed to an instant utility.
- If the player takes another Crate Shower after using the Crate Shower, nothing will happen, which is a waste of crates.
