Water Pool mainly takes place in the sewers of Primus Castle. There are numerous of rat enemies around and poison gas that sprays from areas.
The main objective of this level is to make it to either exit. This level is fairly short and getting around isn't too difficult. Earning the target score may be a little hard due to some out-of-reach gems that only can be gotten to by precise jumping. Near the exit, there are two exits: one on the upper ledge and one on the lower ledge. Taking the exit on the upper ledge leads to Millian Road and the lower ledge exit leads to the Warp Room.
The Adok Bomb in this level can be found on small ledge on the water right by before the two exits. White Bomberman must jumps over the water before he gets on the platform.
