Ignore the pain, you're a sponge; pull the arrow out
From Create Your Own Story
You pull the arrow out and turn around. You step on Plankton killing him instantly.
You lie down on the floor. Some time later Mr. Krab comes in. He is carrying a gun and wants to kill you because he is too niggard to give you a raise.
Stab him in the leg with the arrow and shoot him in the face
