A prototype exists for a US version of the original Japan-exclusive Puzzle Bobble known as Bubble Buster which removes the Bubble Bobble elements outright, as it was a very common practice for puzzle games at the time. This is somewhat unusual, because no replacement characters were provided, unlike localisations such as Tetris Attack, and Bubble Bobble had already proven itself to be a popular brand in the American market at the time. The logo for Bubble Buster would serve as the basis for the logo of the Neo Geo arcade remake's US release, Bust-A-Move, though that did not remove the Bubble Bobble characters.
