LEGO 6140 Crab is an Aquazone Stingrays set released in 1998, containing 78 pieces and 1 minifigure. It builds a one-man Stingrays sub with twin swiveling propellers, a claw arm and a propeller arm, plus a handheld claw for the included Stingray. It includes a storage box for Silver Crystals and four bottom-mounted light elements, tying into the Hydronauts and Stingrays conflict over the crystals. The set is essentially the same model as 6109 Sea Creeper but omits the large manta ray creature included with that release.
A new and sealed Crab is currently valued at around $75, with annual growth of approximately 6%. The average used price is $14 for those in good overall condition. Based on current trends, this set could be valued near $80 within the next year. The 1 included minifig account for approximately 13% of the set's total value.
