Potsy is a ghost elephant who haunts the museum in Ghostbusters Beeline (Mobile app). He attacks by shooting electricity and lands where you stand. The only way to survive his attack is to keep moving. It requires strategy to beat Potsy. Your best bet is to lure him away from you by using your Slime Decoy and use a grenade to stun him, then use proton streams on him. Repeat the process to capture him.
