----- Harden Normal
TMs: N/A
HMs: N/A
Advice: If you catch these at this stage rather than leveling them up to it, you'll get it's infamous Harden technique. This is actually a good defensive measure, but if you level it up from a Caterpie, the Red and Blue versions will allow you to use Tackle and String Shot. For capture, just keep pounding on it until it's hit points are low. Beware, though, because even at low levels, they're really tough to hurt when they crank up their defense.

Advice: Beedrills, if you encounter them, are far more dangerous than Butterfrees as they tend to Focus Energy, then unleash all sorts of special techniques. But, so long as you have a fire or a Rock Pokemon, they can be easily defeated.

Advice: Like the Scyther, it's cheaper to try and get one via the Safari Zone, but if you've got the money, try exchanging cash for it. Beware, though, as it takes 1000 dollars to equal 50 coins if you trade for them outright.
