The Ickle Baby Bot ($3.95) bath bomb is among the smallest in the collection of bath bombs. It has a soothing lavender scent designed to make you sleepy and comes in the shape of an adorable little robot. It fizzes more calmly and quietly than the others and turns the water a pretty aquatic turquoise v . I think it was worth the couple bucks for a nice, relaxing bath. Thanks Lush!
