Rain is a type of trap in Saturn Bomberman.
Description[]
Rain that appears exclusively in the Battle Mode's Jungle Trap and Desert Twister stages. Rain will start falling every 10 seconds and covers the entire screen for 8 to 12 seconds. All the Bombs placed on the screen during the rain period will still be detonated, but their blast power is lowered to only 1 tile (the minimum), regardless of the player's fire blast power.
