Willow Pools

Water seems to be running to almost every place in Riverclan, including the Willow Pools.
The water is located at the bottom, in the cups of muddy mud. However, if not stirred, the water is almost perfectly clear, safe to lap/drink at, and a good place to hunt an appetite of small fishes.
Like the name, Willow Pools includes willows growing straight from the mud and not to mention grass too, either long and straight or small and bushy, they're their located in small islands.
Since it's near The Island, where many cats visit every full moon, you can see the paw prints after the moon has fallen down. Wow! That's A LOT of paw prints, isn't there?
