If you've missed the iconic duo in Pokemon Go, we have some great news for you - Jessie and James have arrived and they are ready to be trounced.
The advice is definitely to keep an eye for a Meowth hot air balloon that is floating around for a limited time. All you need to do is tap the vessel and pummel Ekans and Koffing in a battle. That's it!
Lore-wise, "Team GO Rocket has assigned Shadow Pokémon to protect Jessie and James as they seek to create more Shadow Pokémon." In reality, though, they seem to really appreciate the taste of defeat. We are about to give them that!
