# Room 78: Swamp Island (Cobra/Fruit)

This is the swamp island where a HUGE cobra guards a magical fruit tree. The player must use the flute to hypnotize the cobra in order to retrieve the fruit needed to save their father. The room features a dangerous jump across grass tufts to reach the island, and a snake that blocks access to the fruit until mesmerized.

## Look Description

"You see a small island in the middle of the huge swamp. Upon this island grows a scrawny little tree. %s Unfortunately, a huge cobra protects it."

(Note: %s is replaced with fruit description when present: "A large, glistening fruit hangs from a small branch.")
