  Looks like part [98578 Hero Factory Weapon: Spiked Ball, Half](https://www.bricklink.com/v2/catalog/catalogitem.page?P=98578&idColor=14) in transparent dark blue (found by a bricklink search for pieces named "half" in trans-blue).
  
  [It appears in two sets](https://www.bricklink.com/catalogItemIn.asp?P=98578&colorID=14&in=A): [70202-1 "Chi Gorzan"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=70202-1) from Legends of Chima, and [45560-1 "EV3 expansion set"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=45560-1).
