You'll begin on a now infamous bridge known as "Nugget Bridge". Here, you have to battle your way through a series of 5 Pokémon trainers, with the hopes of earning a juicy gold nugget at the end. At any time, you're allowed to leave and rest up at Cerulean City's Pokémon Centre. Shall we begin?
Bug Catcher Cale
This lad has a new Bug-type that you catch around here. Like Weedle, it's Bug and Poison, so Fire and Flying-types will be great to use. If your partner is Eevee, Sizzly Slide should do a lot of damage to it as well.
Similarly, this lass's Pokémon can also be caught here on Route 24. Since it's a Water-type, Grass-types are ideal and Electric-types are also very good. That can mean Pikachu or a partner Eevee with Buzzy Buzz.
Hopefully you're aware that Electric-type moves don't work on Ground-types. Instead, try to focus on Grass or Water-types. A partner Eevee using Bouncy Bubble is also quite effective here.
This Meowth can surprise you with Fake Out, which always goes first and causes your Pokémon to flinch. But it only works on the very first turn. After that, just pummel it with your hardest hitting moves, ideally of the Fighting variety.
This trusty canine is a Fire-type and thus weak to Water, Rock and Ground-types. The likes of Geodude and Onix will be appreciated here. A partner Eevee can also douse it with Bouncy Bubble.
Having cleared all 5 trainers, you'll receive a Nugget from the man waiting at the end, which you can sell for a tidy profit. But it turns out the man has sinister intentions for you...
Team Rocket Grunt
This Grunt has Team Rocket's trademark Poison Pokémon. For Zubat, Electric and Rock-types are the way to go. Both of your partners can shine with their Zippy Zap and Buzzy Buzz. For Koffing, anything goes, but please put aside your Grass-types for the time being.
After smashing the Grunt's dreams, continue onwards towards the north-west corner of this area. Over here is a negligent trainer and his Charmander. If you've caught a total of 50 Pokémon, he will give you his Charmander. Depending on how you've been playing, you might be far from 50; if so, make a mental note to come back.
East from here is Route 25, where our next destination is. Before going that way, head south while keeping towards the west. You'll find a patch of tall grass, with a young trainer keeping guard. If you time it right, you can sneak past him.
A weak bird Pokémon. If you want to show off, throw some Rock or Electric-types its way.
Carry on south through the patches of tall grass. In the far corner are 3 Razz Berries that nobody else is going to pick up. Further south, you can return to Route 4 and reach the entrance to the postgame dungeon. But you'll need a way to travel across water.
For now, double back and head east towards Route 25.
Venonat and Psyduck should be your first focus. Neither of them are essential, but they're good for padding out your Pokédex. Those playing Let's Go Eevee can also encounter Meowth here. We'll remind you later, but we strongly suggest catching at least 5 Meowth.
In terms of rare spawns, there's Squirtle to be found. That makes all three of the original starter Pokémon. Like the other two before it, you can earn a Squirtle for free, provided you catch a total of 60 Pokémon. You'll also need to wait until after completing the Cerulean Gym.
