Floatzel has many traits similar to a weasel, hence it being the 'Sea Weasel Pokémon'. It has a flotation sac on its back, which makes this Pokémon look a lot like a rubber floats. There are two blue fins on its arms, and it has two tails.
Male Floatzel have two spots on their back while females only have one. This is the same case for Buizel.
It has the ability Swift Swim. Swift Swim raises its speed in rain. It is known to be a very fast swimmer, and it saves the lives of drowning people by inflating its dinghy-like collar to create a surface to rescue them.
Floatzel is the evolved form of Buizel, which can evolve into Floatzel at level 26.
