Pokémon Red and Blue/Mt. Moon

New Pokémon Available

Red	Blue	Yellow
Zubat Geodude Paras Clefairy

Mt. Moon is crawling with all sorts of new Pokémon as well as several menacing members of Team Rocket. Team Rocket is after Pokémon fossils, no doubt as part of some diabolical scheme. It's up to you to stop them from raiding these lost paleontological treasures!

Mt. Moon Battle Tactics

This cave is full of Zubats, but once you put a Pikachu or Spearow at the head of the roster, you'll find them to be little more than an annoyance. Deeper levels of the dungeon have Zubats that use the Supersonic skill to confuse your Pokémon, but that can be shaken simply by swapping the confused fighter for another.

Geodudes are a bit trickier. They're weak to Grass and Water, so Squirtle's Bubble and Bulbasaur's Vine Whip can wipe them out quickly. But if you don't have either of those guys, you can just grab TM 12 and use it to teach Water Gun to one of your Rattatas, Jigglypuffs, Nidorinas or Nidorinos. Remember that Poison and Rock-type attacks don't do so well against Geodude, and Electric attacks have no effect at all.

Feel free to equip the TM 01, which is Mega Punch. It's a pretty powerful Normal-typed attack, if slightly inaccurate. It will be outclassed by other attacks such as Strength, Body Slam and Double-Edge later on.

More Battles Await

Two nasty surprises await at the end of Mt. Moon (to get to the end, take ladder C to F to G). Blue and Red players may simply want to avoid Rocket #3, since his level 16 Raticate can easily slay a half-HP starter monster with Hyper Fang. Yellow players can't avoid their extra battle, though. Use an Escape Rope and come back with a healed party, or heal up with Potions as needed. Yellow players should also watch out for Jessie and James, who will ambush you at the end after the battle over the fossils.

Which fossil should you take? When you get the Dome Fossil cloned (much later in the game), it will become Kabuto. The Helix Fossil will yield an Omanyte. You can't go wrong with either one, since chances are you won't want to exchange a member of your high-level team by that time. To get the other one, you'll either have to trade for one, or receive one as a prize in Pokémon Stadium.

Secrets of the Moon Stones

The Moon Stone you picked up in Mt. Moon is a crucial item, and one of only five Moon Stones in Pokémon's world. Moon Stones are the one and only way to make certain Pokémon evolve, of which there are exactly four: Nidorino (Nidoking), Nidorina (Nidoqueen), Jigglypuff (Wigglytuff) and Clefairy (Clefable). But don't go burning that Moon Stone quite yet: all four of these Pokémon basically stop learning skills once they're evolved, so before you evolve any of them, check the Pokédex and make sure they've learned all the skills you want out of them. Note, though, that all four can still learn a wide variety of skills from TMs and HMs.

There is one Moon Stone here in plain sight, and another hidden in one of the basements. Before you take on Trainer #5 near the two fossils, search the dead end marked D for a second Moon Stone.

#41 Zubat	#74 Geodude
Zubats aren't really that exciting. They're Flying and Poison-type (even though they don't learn any Poison techniques), so they're weak to many types. Leech Life's draining ability is cool, but is extremely weak at 15 power. You'll be hard pressed to damage most things with it.	Geodudes can be painfully slow, and their dual weakness to Grass and Water can be devastating. However, their Attack and Defense can grow to high-tiered levels, and they can gain Rock and Ground attacks without the use of TMs. Their strength versus Electric, Flying, Fire and Normal attacks is also very useful throughout the game.
#35 Clefairy	#46 Paras
Clefairys and Jigglypuffs are very similar; both are big, puffy Pokémon that evolve with a Moon Stone, have a ton of HP, and can use just about any Technical Machine. However, Clefairys have much better stats overall. They aren't very useful for adventuring, but can become fairly strong with TMs for link battles.	A unique Grass/Bug combo, Paras is very weak in general. Many tout him as a "Psychic stopper", given his Bug status, sans a Poison-type, and his Leech Life Bug-type attack. Unfortunately, this just isn't the case. Leech Life is extremely weak no matter what, and his stats are rock-bottom. His only saving grace is Spore, a Sleep-inducing attack which has a nearly 100% accuracy. But since Paras (more likely Parasect) is so slow, you will likely lose most of its HP before landing it.
