Poipole is perhaps the strangest Ultra Beast because it can evolve. And with Naganadel's addition to Pokémon Go, all you need to do is put in a little effort to unlock the little guy's full potential.
How to eventually evolve Poipole into Naganadel in Pokémon Go.
Initially, Poipole couldn’t evolve into Naganadel in Pokémon Go due to a phased release, similar to how Cosmog and Cosmoem delayed the availability of Solgaleo and Lunala. That restriction has now been lifted, and you can evolve the Poison Pin Pokémon, though the evolution method is unorthodox. If you’re looking to fully evolve UB Adhesive, read on to learn how to get your Poipole into Naganadel in Pokémon Go.
To evolve Poipole into Naganadel in Pokémon Go, you'll need to have 200 Poipole Candy and set Poipole as your Buddy Pokémon. From there, you'll need to catch 20 Dragon-type Pokémon before giving it the Candy.
This is an odd evolution mechanic that Niantic likes to use, requiring you to actively engage your Pokémon in activities like catching Pokémon or battling other players. Evolving Primeape into Annihilape requires a similar amount of attention, though Poipole is a bit more intensive as it’s harder to get the required Candy purely due to the Ultra Beasts being rare species.
