Drop the tank and run out of the room
From Create Your Own Story
Jessica dropped the tank to the floor and staryed swinging her arms around at the creature. Melvin fell to the floor with a slapping squish between Jessica's feet. Another shriek from Jessica saw her running for the door leaving professor Bates shouting after her whilst picking Melvin from the ground.
Jessica started running down the corridor with her breats swaying freely and reaching the top of the stairs sliding on the remains of water on her feet.
