Ice Bomb

An Ice Bomb is an attack item in Super Mario RPG: Legend of the Seven Stars. It can be purchased in Seaside Town (before fighting Yaridovich) or obtained as a possible reward from defeating Muckles or Machine Made Bowyers. It can also be obtained by using Yoshi Cookies on certain enemies. Using an Ice Bomb in battle deals 140 points of damage to all enemies. It deals double damage to enemies weak against ice, and 0 damage to enemies immune to ice. If a character has the "Attack Up" effect, such as from Geno Boost or the Quartz Charm, the damage output is increased to 210.

In The Super Mario Bros. Super Show! episode "Koopa Klaus", Koopa Klaus himself uses Ice Bombs to freeze over Santa's workshop. However, the Ice Bombs in question are never seen, leaving their actual appearance a mystery.
