"Crab" was an officially licensed t-shirt designed by Brandon Bird and Tyler Jacobs, released in 2005 for the release of 'Charge!!'. It came in dark brown, hot pink and turquoise. The design features a cartoon version of the band riding a giant mechanical crab, with "THE AQUABATS!" in Japanese print and the word "Charge!!" underneath.

As of 2009, only the brown version is still being sold by the band.
