Pokédex entries

RedBlue A brutal POKEMON with pressurized water jets on its shell. They are used for high speed tackles.
Yellow Once it takes aim at its enemy, it blasts out water with even more force than a fire hose.
Stadium It has spouts extending from its shell at the top. They spray water like cannons, hard enough to pierce concrete walls.
GoldStadium 2 It deliberately makes itself heavy so it can withstand the recoil of the water jets it fires.
Silver The rocket cannons on its shell fire jets of water capable of punching holes through thick steel.
Crystal It firmly plants its feet on the ground before shooting water from the jets on its back.
