BANDAI has announced a new Mobile Suit Gundam release for its wildly popular Bikkura Tamago bath bomb toy line. Bikkura Tamago Mobile Suit Gundam is scheduled to launch on December 15, 2026.
BANDAI launched the Bikkura Tamago line in Japan in 2002, and the collectible bath bombs remain hugely popular more than two decades later. Originally aimed at children, the series has since expanded its audience to include adult collectors, with themes spanning hit anime, classic movies, idol groups, and adorable food designs. Each release features a differently shaped bath bomb based on its theme, with a random mini toy hidden inside. As the bath bomb dissolves, collectors get the same surprise as opening a capsule toy—all while enjoying a relaxing soak.
Bikkura Tamago Mobile Suit Gundam revives the classic 2009 Bikkura Tamago SD Gundam release with updated packaging. The bath bomb once again takes the shape of Haro, the signature robot mascot of the Gundam Series. Once Haro dissolves in the water, it reveals one of six randomly packed SD-scale Soft Vinyl mobile suit figures from the original Mobile Suit Gundam series: RX-78-2 Gundam, GM, Char's Z'Gok, Acguy, Zaku II, or Char's Zaku II.
