Trivia

 * Strangely, It is a normal type Pokémon that can learn water type moves and it evolves into a water type Pokémon which is Marill.
 * It is one of the only two baby Pokémon in the Generation III games, the other is Wynaut.
 * Azurill is very unique in the fact that it's gender ratio is 1 male to 3 females, while it's evolutions, Marill and Azumarill, have a gender ratio of 1 male to 1 female, due to this if a female Azurill evolves into a Marill it has a 1 in 3 chance of changing from female to male due to the differences in gender ratios.
 * Azurill is one of the 2 Pokémon you can get in Pokémon Fire Red and Leaf Green without trading from Ruby, Sapphire or Emerald. The other Pokémon you could get is Wynaut.
