There are no official ways to obtain Celebi in that specific game. Celebi is a Pokémon that is primarily associated with the *Time & Space* series of *Mystery Dungeon* games.
Here's why you can't get Celebi in *Blue Rescue Team*:
* Game's Release: *Blue Rescue Team* was released before Celebi was introduced to the *Mystery Dungeon* franchise.
* No Event: There were never any events or special distributions that allowed players to get Celebi in *Blue Rescue Team*.
Where to Find Celebi in Mystery Dungeon:
* Time & Space Series: Celebi is a central character in *Mystery Dungeon: Explorers of Time, Explorers of Darkness, and Explorers of Sky*. You can recruit Celebi through the main story in these games.
* Super Mystery Dungeon: Celebi also appears in *Super Mystery Dungeon* and can be recruited later in the game.
Keep in mind: *Mystery Dungeon Blue Rescue Team* is a great game, but you won't find Celebi in it!
