Getta 3 is the "underwater" combination of Getta Robo. Much smaller in size than the other two combinations, it was unpopular and sold poorly when it was released. As such, it is the rarest of the three Getta Robo chogokin toys. It is also one of the smallest Popy pieces.

The earliest versions of the Getta III toy featured plastic arms, but this was changed to polyethylene for later releases.
