Floatzel is an orange Pokémon resembling an otter or a weasel. It has two pointed blue fins on its arms and two tails. The yellow flotation device gives the impression of an inflatable life vest. When it lays on its back, the flotation sac could also be interpreted as a sort of inflatable dinghy using its tails as a propeller and its fins as oars. Its forelimbs and tails are tipped in cream, and there is an orange teardrop shape in its cream lower belly. Floatzel also has a circular cream spot in the center of its head, cream eyelids and a pattern of two black triangles on the edges of its cream muzzle. It has one cream spot if it is female and two if it is male. It can use its swimming capabilities to assist in the rescues of drowning people. It tends to inhabit swift-moving rivers. Some believe Floatzel is a fish-eater.
Floatzel, the Sea Weasel Pokémon and the evolved form of Buizel. Its flotation sac developed as an aid in chasing aquatic prey. Floatzel can also carry people on its back.
In Pokémon Adventures, a Floatzel is first seen acting as the motor jet for Professor Rowan and his assistant (Platinum's father) as they arrived in Canalave City. Later, Crasher Wake has a Floatzel, which he used to battle Platinum's Empoleon, but after a close battle, lost. A few volumes later, under Wake's command, Pearl attempted to catch one himself, but failed to do so and resorted to catching the weaker Buizel.
Floatzel is based on an otter, which is in the same family as weasels, however it resembles weasels a little more closely than it does otters. Floatzel also appears to be loosely based on the Kamaitachi.
