No, but during a song, a character holds a ping pong ball up to his eye and hits the back of his head (gently), throwing the ball in order to mimic his eye popping out. Very clearly not like the real thing at all
Okay so idk if this is really self-harm?? But it's worth noting that a character alters a band on his wrist to improve his physical performance, but it hurts after a while of usage. He's aware of this and continues using it not BECAUSE it hurts, but in spite of it
In the brief backstory at the beginning of the movie, it's mentioned (and shown through very basic drawn images) that a power plant exploded, causing zombies. It's portrayed in a very unrealistic and even humorous light
