Crate

Crate is one of the item containers that can be broken with any weapon or the sword to get the item contained inside. It can be just a single crate or a group of stacked crates. Normally, crates contain one item, which can be a treasure (or a coin) or an ammunition (ammo, magic or dynamite). Enemies can also crush crates, however this may cause an item contained inside to fall to the water or spikes, so the item will disappear.

Crates require only one hit or shot to get crushed. However, level editors can configure crates to require two or more hits or even make an empty container in their custom levels.

Trivia
The twelfth level, Undersea Caves, is the only level in the game which lacks any treasure containers. Instead, all treasures are already scattered around on the level and can found from enemies.
