Red X and Core-X both replenish 10 bombs. * Metroid: Zero Mission - Resembles Super Metroid's take; still replenishes one bomb. * Metroid Prime - Small yellow sphere with pink-ish energy emanating from it; replenishes one bomb. * Metroid Prime 2: Echoes - A round object that glows yellow; replenishes one bomb.
