Hi there! I'm a seasoned Pokemon trainer with years of experience under my belt. I've traversed Kanto countless times, raised numerous Pokemon to championship level, and even dabbled in a bit of Pokemon breeding. People often come to me for advice, and I'm always happy to help guide the next generation of trainers. You've come to me with a question about a particularly electrifying move in Pokemon Yellow – Flash. Let's dive into that.

So, you want to illuminate the dark caves of Kanto, huh? It's a necessary step in your Pokemon journey. Now, acquiring Flash in Pokemon Yellow is a bit different from other Pokemon games. You see, there's a common misconception that Pikachu, your trusty partner, learns Flash. Unfortunately, that's not the case in this version.

The responsibility of learning Flash in Pokemon Yellow falls upon the electric rodent Pokemon, Pikachu, that you can catch in Rock Tunnel. Here's the breakdown:


1. Head to Rock Tunnel: You'll find Rock Tunnel located on Route 10, just north of Lavender Town.

2. Navigate the Darkness: Before entering, make sure you have some way to navigate the darkness. People often use a Escape Rope to escape immediately and use the Pokemon Center outside to heal up.

3. Encounter and Capture Pikachu: Inside Rock Tunnel, wild Pikachu can be found. It might take a while, but be patient and keep battling until you encounter one. Weaken it carefully and use a Poke Ball to catch it.

4. Teach Flash: Once you've caught your Pikachu, you'll need to teach it Flash. Head back to the Celadon City Department Store and purchase TM25 (which contains Flash). Now, simply teach the move to your newly acquired Pikachu.

Now you have a Pokemon that can light up even the darkest corners of Kanto! Remember, Flash not only helps you see in caves but also makes it easier to find hidden items.

There you have it! I hope this clears up any confusion about obtaining Flash in Pokemon Yellow. Remember, every journey is different, and part of the fun is figuring things out along the way. Good luck with your adventure, trainer!
