Head straight for the chest

From Thread 1

Fred heads for the treasure chest floating above the water. Unfortunately, the water is very deep and Fred sinks to the bottom.

• Fred swims upwards and grabs onto the chest.
• Fred is sucked into an underground current.
• Fred drowns.
• Fred tries to grab the chest, even though his own chest is empty of air.
• Fred grabs onto a dolphin that was swimming by.
