Negroka Ball

About
Negroka Ball is a Ball that can be eaten and make you jump 3 blocks high perminently unless you are dead. It is not a food and it does not restore any hunger bars. Once you ate it, it will not come off until you are dead. You can jump over mobs except Endermen (and equivalents), Fire Golems or Iron / Diamond Golems. If underwater, you will swim up quicker. To get them, you need to kill a Negrokaman or a Negroka Whale.
