Get ready for a whole bunch more Trainers, although there are also some neat new Pokémon in the area for you to catch if you didn’t get any on Route 24. The Pokémon on Route 25 are a bit higher level than their counterparts on Route 24, but the selection and encounter rates are both identical.

Hiker Franklin guards the small patch of grass on the route, although you can sneak past him if you’re careful. Head over to the patch of grass, pick up any Pokémon you’re interested in, and then grab the X Sp. Def near the end of the ledge — it’s technically on Route 24, sure, but you can only reach it from Route 25.
Going back east, there are still a lot more Trainers to fight. Youngster Chad and Bird Keeper Joey are right after Hiker Franklin. Joey might be a bit more challenging than the other Trainers around due to having a Pidgeotto at level 15, although your partner Pikachu with Zippy Zap or partner Eevee with Buzzy Buzz will make short work of it. Don’t forget to pick up the Super Potion to the left of Youngster Chad.
Moving right along, Youngster Dan and Hiker Nob are right around the corner. Take them down and then keep going. Getting tired yet?
Pay careful attention to the upcoming Picnicker and Camper. You can get an item early if you position yourself properly. Approach Picnicker Kelsey and keep her from moving towards you by either talking to her or just walking directly in front of her. After you’ve beaten her, walk directly south of Camper Dustin and then walk north until he walks towards you. Then, once you’ve beaten him, you can walk behind him and grab TM16 Thunder Wave — an Electric-type move that paralyzes the foe. If you don’t get Camper Dustin to move right, you won’t be able to get TM16 until after you’re able to chop down those small trees.
You’re almost at the end! Keep going forward, grab the Ether down in the corner of the hedges to the west of the next Trainer, then go over and fight against Lass Haley. One more Trainer to go and that’s Fisherman Wayne. Take him down and then you’ll finally arrive at Bill’s cottage.
Before you go inside, there’s a Coach Trainer waiting for you to the right of his house. If you’re feeling up for the challenge, you can take her on.
1600Her Machop makes use of the move Seismic Toss, which deals a fixed amount of damage equal to its level — in this case, 16 damage exactly. It isn’t affected by weakness or resistance either. After beating her, she’ll give you TM15 Seismic Toss, which, yeah, just explained what it did. Most of the time that’s not going to do more damage than your normal moves, but it can work well on Pokémon with weaker offense like Chansey to deal a consistent amount of damage while taking virtually none in return (at least for Special-based damage, in Chansey’s case).
Don’t forget to pick up the Lure in the bottom right corner of the route before heading into Bill’s cottage.
Anyway, now that you’ve cleared Route 25, make your way inside of Bill’s cottage. Upon entering, your partner will notice a Nidorino in the corner. However, that’s not just any Nidorino — it can speak humanspeak! Apparently Bill screwed up an experiment and got turned into a Pokémon as a result. Offer to help him out and then you’ll need to examine the PC in the room.
Before doing so, you can also shake your Joy-Con or Poké Ball Plus to see a scene with your partner Pokémon acting a little confused about the situation.
You’ll get a little cutscene after activating the Cell Separation System on the PC and Bill will return to his human self. He’ll reward you with some S.S. Tickets and then tell you about the S.S. Anne in Vermilion City that hosts parties, but he isn’t interested in going, so he gave you a few of his tickets so you can go and share with a friend.
If you really want a funny scene, shake your Joy-Con or Poké Ball Plus once again when prompted and your Pikachu or Eevee will be incredibly shocked at the outcome of the computer experiment.
Now that you’ve got the S.S. Ticket, you’re free to return to Cerulean City and then take on the Gym. On the way back, though, be on the lookout for 3 Pinap Berries that are hidden in a bush to the east of Nugget Bridge.
