"Super Mario Bros. Bath Bombs by Lush Bring Nostalgia and Controversy"

Lush's collaboration with Super Mario Bros. for bath bombs has been criticized for turning bath water into a "pee yellow" color. The bath bomb contains one of six Mario-themed body soaps inside of it, to be revealed after it dissolves. The ingredients for this specific product are not specified, but Lush's bath bombs are usually made of baking soda, a secretive "bubble mix," citric acid, and essential oils. The bath bomb is available for $18 and includes a soap shaped like the big mushroom, the little mushroom, a coin, an ice flower, a fire flower, or one of the "rarest" yellow stars.
