S'hdu (Shaedoo) are probably the smallest Grynd workers. They operate very close to their teammates, H'xu (watch the previous upload), by collecting relatively small pieces of mineral with their front limbs. Due to their size, they can clean their colleagues, reaching impossible corners and angles. This ensures the correct functionality on those big bulldozer beasts. S'hdu have great power on their back legs, allowing them to jump great distances like a grasshopper would do. Their other 4 legs grant them great grip while climbing rock walls or even the huge bodies of their H'xu friends.
Here are some design process of this creature I created when working at Catness Game Studios on HIVE: Altenum Wars
