Bikkura Tamago (びっくら？たまご lit. "Surprise Egg"), more commonly known as "Soap Figures", are unique chibified figures that come in soap Pokéballs that dissolve in bath water. Produced by Bandai, these figures can quickly become quite rare because of their unique way of blind packing. Originally only distinguishing by being weighted, since the series continued into the DP era they've gained very distinctive loops that can turn the figures into keychains. The figures are also no longer weighted.
