Location from Club Penguin by New Horizon Interactive / Disney
A subterranean lake beneath the island — where underground rivers meet the open sea and sunken treasure drifts in with the current.
The Hidden Lake is Club Penguin's most beautiful secret. It's a subterranean body of water that connects to the open sea through an underwater passage, meaning treasure and debris from the ocean floor drift in on the current. Waterfalls pour from underground reservoirs, and the light that filters in from the sea entrance creates an otherworldly blue glow. Finding the Hidden Lake felt like discovering something the game hadn't meant to show you — even though it was always there, waiting. It's the room that proved Club Penguin's island had depth, literally and figuratively, beneath its cheerful surface.
A vast underground cavern housing a still, dark lake. Waterfalls cascade from underground reservoirs above. The cave opens to the sea at one end, letting shafts of blue light penetrate the darkness. Sunken treasure and driftwood float in the shallows. Stalactites drip from the ceiling. The water is impossibly clear.
