The Sunset Cliff is an area accessible from a cave in the Windy Canyon.
This area features a cliff facing a sunset, a rabbit sitting on one of the two beach chairs facing said sunset, a sandcastle, a pink bikini and a beach towel. At the very right of the screen is a hole that will take the player to Isle of Seasons while the door in the cliff on the left side of the screen will take the player to Windy Canyon.
Muma can sit on the empty chair, and after enough time, Muma and the rabbit will hold hands. Exiting the area after holding the rabbit's hand has a chance to trigger the True Sunset event. Note that completing this event will make the rabbit, the sandcastle and the beach towel disappear permanently.
