Following on from all past Pokémon Rumble titles, Pokémon Rumble World includes the capability to use passwords. To do this, when in the courtyard press Start and select the Password option. If you have an Adventure Rank of 4 or higher, you'll be able to enter passwords.

The Pokémon you receive will be distributed via various means, but you will have access to them straight away.

While these Pokémon are mostly low levelled, they are useful in getting certain moves into the movepool which allows for your stronger Pokémon to obtain them via the Move Tutor.
