Background story: After losing their instinct by being raised by survivors, a genius dude think of a robotic legs supporter will help the crab be like their brothers (GOD FREEAKING SAND CRABS) but this prorotype can only make the crab jump higher instead of LEAPING
Cost: around 10K Rank: 0
Type: Supporter thing
Effect: These robotics thing help them raises their jump height by 10 (UPDATE, it will also increase the crab's speed by 3-5)
Feel free to criticize it. And find a name for it pl0x
and sorry for my broken english
