River Cave

The  was a party room for the Operation: Puffle party. As such, it could only be accessed from November 22, 2018 until December 6, 2018 when the party was active on Club Penguin Online.

Trivia

 * Whenever you go onto the river, a boat will appear as if you are riding it.
 * Unlike the water at the Cove and Hidden Lake, the dark water isn't "cut up", so you're always underwater fully unless you're close to the sides.
 * Walking to the lights will turn them on.
 * This is where you rescue the Yellow Puffle and Purple Puffle.
