Pokémon Red and Blue: Cerulean City

If you are playing on a Super Game Boy or Game Boy Color, then the first thing you will notice about Cerulean City is its eponymous blue color.

Starting right off, the man in the northwestern house will tell you the unique benefits of each of the region's gym badges. The BoulderBadge you already have increases your Pokémon's Attack by 10% and allows you to use the HM move Flash outside of battle. The next badge, the CascadeBadge, will allow the use of Cut outside of battle, and will make traded Pokémon obey your commands up to level 30, where they might otherwise refuse to attack, use the wrong move or go to sleep in battle. Go through the back door of this house and examine the area behind it to find a hidden Rare Candy.

The house next to the gym contains a man who wants to trade the only Jynx in the game for your Poliwhirl. Both of these Pokémon will be explained when Poliwhirl becomes available.

The southwest building is a steeply priced bike shop. You can never have more than P999,999, so the P1,000,000 bike is off limits to you for now.

The Pokémon Mart sells the following items:

• Poké Balls - P200, be sure to stock up.
• Potions - P300
• Antidotes - P100
• Awakenings - P250
• Burn Heals - P250
• Parlyz Heals - P200
• Repels - P350, these would have been most useful before the cave, because they prevent you from encountering Pokémon of a higher level than the one at the top of your party for 200 steps a can.

You have two options here. You can enter Cerulean's Gym Gym (which is really just a Gym) or you can head north onto Route 24. You can get as far as the next town without collecting Cerulean's Gym Badge, but you won't be able to advance to the third badge until you get this one.

Enter Cerulean Gym

Proceed to Route 24

Pokémon Red and Blue: Pewter City

There is little to do in Pewter City beside healing up at the Pokémon Center. The Poké Mart does contain one new item.

• Poké Balls - P200, it's always a good idea to stock up on these.
• Antidotes - P150
• Awakenings - P250, these will heal the Sleep status ailment. It would not be a bad idea to pick up one or two.
• Burn Heals - P250
• Parlyz Heals - P200
• Potions - P300
• Escape Ropes - P550, these items can be used outside of battle and will return you to the doorstep of the last Pokémon Center you used. Their best use is when you are deep in a cave with low health. Note that they are frequently found inside such caves for free.

If you want to brush up on your history, head into the Pewter Museum of Science, to the north; however, this is not required for anything and costs P50.

When you're finished exploring. Enter the gym.

Enter Pewter City Gym

Pokémon Red and Blue: Viridian City II

Now that your ability to get free stuff is no longer in jeopardy, I will go over the Pokémon Mart stock in Viridian City. You can buy:

• Poké Balls - P200, I recommend stocking up on these, because many Pokémon can be caught in the next few areas.
• Antidotes - P100, these will heal the Poison status ailment; however, many of them can be found for free.
• Burn Heal - P250, these will heal the Burn status ailment, but you will not encounter this ailment for quite some time, at which point better items will be available.
• Parlyz Heal - P200, these will heal the Paralysis status ailment, but you won't encounter this for a while either.

After restocking, head back to Route 22 to catch some more Pokémon.
