The Boss Curcubitor has two skills to defend itself:
The first skill (indicated by a red halo) reverses the controls of the ship that is hit. So when one tries to fly up, it will go down instead, etc.
The second skill (indicated by a green halo) is a sticky bomb that gets fired onto the selected player and sticks to his or her ship. It then has a countdown of 10 seconds before exploding, just like a mine. Can do up to 120k damage.
