The Sandy Isle
The Sandy Isle is a small island in the middle of a wide river in PuddleClan territory. It is used by the PuddleClan cats as an apprentice training area. It uses the same kind of defense as their camp which of course seems like very little but is a lot more. Apprentices are taught to swim by making them cross the river to the training ground. It is how PuddleClan cats always end up being the best swimmers of them all.
