Gundam’s Official Mobile Suit Bath Bomb Collection Returns After 17 Years
Bandai is bringing back one of Gundam’s classic novelty toy collections after 17 years, with pre-orders officially opening for a series of bath bombs containing miniature Mobile Suit figures from the original anime.
“Bikkura Tamago Mobile Suit Gundam” revives Bandai’s original November 2009 SD Gundam bath toys, with six miniature Mobile Suit sculpts appearing inside specially designed bath bombs shaped like the franchise’s popular Haro mascot.
Bikkura Tamago is Bandai’s long-running bath bomb series, first introduced in 2002 and subsequently expanded to include characters from numerous popular anime, games, and entertainment franchises.
Each bath bomb contains a randomly selected miniature figure that is revealed when the outer shell dissolves in warm water, combining the surprise of capsule toys with a novelty bath product.
Haro first appeared in the original 1979 Mobile Suit Gundam anime as a small spherical robot created by Amuro Ray, bouncing and rolling around while interacting with the crew of the White Base.
Its round green body, playful personality, and ability to repeat short phrases made it one of the anime’s most popular supporting characters, with different versions of Haro appearing throughout subsequent Gundam series and becoming a recurring mascot for the franchise.
For the returning Bikkura Tamago collection, Bandai has recreated Haro as a dissolvable bath bomb, complete with the character’s eyes and mouth across its surface, alongside updated packaging for the revival.
Once placed in water, the bath bomb releases a muscat fragrance, replacing the original collection’s forest-inspired scent, and turns the surrounding water pale green before revealing one of six miniature soft-vinyl Mobile Suits.
The collection includes the following figures, each featuring the simplified proportions of Bandai’s original SD Gundam designs.
- RX-78-2 Gundam: The Earth Federation’s legendary prototype Mobile Suit piloted by Amuro Ray.
- GM: The Federation’s mass-produced Mobile Suit developed using technology from the RX-78-2 Gundam.
- Char’s Zaku II: Char Aznable’s customized red version of Zeon’s iconic Zaku II.
- Zaku II: The standard green Mobile Suit used extensively by the Principality of Zeon.
- Char’s Z’Gok: The red amphibious Mobile Suit piloted by Char during the attack on Jaburo.
- Acguy: Zeon’s amphibious Mobile Suit used for underwater operations and infiltration missions.
The inclusion of both the GM and Char’s Z’Gok recalls their famous encounter during the Battle of Jaburo, when Char’s amphibious Mobile Suit destroyed a Federation GM by driving its enormous claw straight through the machine.
The attack became one of the most memorable moments involving Char’s Z’Gok, with Bandai even recreating its three-pronged claw as part of a recent official cushion collection, alongside a second cushion based on the Mobile Suit’s rounded red head.

Pre-orders for “Bikkura Tamago Mobile Suit Gundam” officially opened through Premium Bandai Japan on November 11, 2026, with each bath bomb priced at ¥715 (approximately $4.50 USD / £3.40 GBP).
The collection is scheduled for general release across Japan on December 15, 2026, with availability planned through major hobby goods retailers, drugstores, and general toy shops as well as online retailers including HobbyLink Japan.
No official US release through Premium Bandai US has been announced at the time of writing, though many Bikkura Tamago collections do eventually get general retail releases in the US and other international regions.
