Rubbish

One of the most commonly appearing items around all regions in Rain World, rubbish can take the form of rocks, cogs, bolts, and other pieces of junk, all functionally identical. Rubbish can be thrown at enemies, killing bats and briefly startling or stunning larger predators. Rubbish can also be thrown to distract sound-sensitive creatures like Daddy Long Legs, but by the same token, throwing them may attract the attention of sound-sensitive creatures, including lizards. Hitting creatures such as scavengers with a rock will also slightly anger them, though not nearly so much as hitting them with a more damaging weapon will.

While throwing rubbish does a non-zero amount of damage, it is utterly insignificant relative to the health values of most creatures, making it unable to kill anything but bats. However, it is highly useful for stunning creatures, especially lizards, which will not only be briefly stunned by rocks but will also flip over to reveal their vulnerable stomachs when hit in the head by rubbish.
