Lotad

Lotad (ハスボー Hassboh) is a /-Type Pokemon that evolves into Lombre starting at level 14. Lombre can then evolve into Ludicolo with the use of a Water Stone.

Biology
Lotad is both an aquatic and a land-dwelling Pokémon, found in the Hoenn region, with a lilypad on its back. This species lives in groups at ponds, with their bodies submerged while suspended at the surface by their buoyant leaves, as a measure of hiding from predators. When on dry land, Lotad scuttles towards other ponds because its leaf is too heavy to support, in contrast to Lotad's ancient ancestors which were one primarily land-dwelling Pokémon.

In the Anime
In the Pokémon anime, a Lotad becomes one of the Pokémon in trainer Brock's possession in the third-generation Hoenn story arc in a development considered ironic because previously Brock primarily used Pokémon of the Rock and Ground types. His Lotad eventually evolved into Lombre, and then Ludicolo. Other than Brock's Lotad, many Lotads have been seen where Brock caught his.
