Catching a Buizel in Pokemon Diamond
Buizel; the Sea Weasel Pokémon
There are many varieties of Pokémon throughout Pokémon Diamond. If you are looking for a Water-type Pokémon that is common and easy to catch, then look no further than Buizel. Buizel is a basic Pokémon available early on in the game. It has one evolution, Floatzel, and can learn useful Hidden Machine (HM) moves such as Surf (HM03), Strength (HM04) and Waterfall (HM07).
Locations in Diamond
There are various locations throughout Pokémon Diamond that a Buizel can be found. They are all found in the grass at the locations at any time during the day. The first location is on Route 205. Here the Buizel are a common sight with levels around 8-13.
Right off of Route 205 is the Valley Windworks. A more industrialized area providing wind energy, the Buizel here are common with levels floating around 7-9.
After the Valley Windworks, a Buizel will not be encountered until Route 213. They are still a common Pokémon, but the levels are much higher now, around 20-21.
The last location that you will be able to catch a Buizel is at Route 224.)(*Here the Buizel will be harder to catch because encountering one will be uncommon. Although, if you manage to catch one, you will have the game’s highest level Buizel that is wild that Pokemon Diamond offers hovering around Lv. 23
Catching a Buizel
Here comes the fun part. Once you have run into a Buizel there are some things you need to do before you throw that Pokéball.
Make sure that it is the gender you want and at the level you are looking for. Then you have to weaken it. Water is weak to Electric- and Grass-type Pokémon, so use moves of these types to weaken it quickly. If your Pokemons level is higher than it though, be careful, you do not want to knock it out accidentally.
You want to weaken it to the point where its Hit Points (HP) has dropped into the red. False Swipe is a great move for this since it will always leave a Pokémon with 1 HP, even if it would have knocked it out otherwise. It also helps to put it to sleep using moves like Sing, or paralyze it with moves like Thunder Wave, but they are not necessary. Being affected by these Special Conditions will make it easier for you to catch any Pokémon, not just a Buizel.
Once you have weakened the Buizel, it is time to use a ball. At the beginning of the game you will only have Pokéballs available for use. As the game progresses you will want to use better balls such as Great Balls and Ultra Balls. There are specialty balls available as you defeat more Gym Leaders, as well. Out of these balls, the Net Ball, which works well on Water- and Bug-type Pokemon, and the Nest Ball, which works well on lower level wild Pokemon can come in handy depending on how far in the game you are.
Good Luck and Happy Catching!
