Cartoise's diamond shell attracts the attention of Sableye. Once they realise that it is far too big to eat, these Sableye stick around to help Cartoise by loading gemstones into its cannons, which it then fires at foes using pressurized water.
The waterspouts that protrude from its shell are highly accurate. Born from the high temperatures and pressures deep underground, it defends itself by firing beams from the jewel part of its body.
