there are alot like in the lake of rage
in safari zone using the "peak" areas
the Pokemon that are in that place may be"poliwag,poliwhirl,sandslash,sandshrew,sentret,kangagaskan and so on.
Most rare Pokemon are located in scattered area such as Suicune, Riakou, and Entei, but if you are looking for Ho-oh and Lugia they are located in distinct areas pertaining to your version of the game (HeartGold and SoulSilver).
It is probably a cheat
Technically you yous a super rod in some areas e.g. behind the gym in blackthorn city.
The literal games that came before Pokemon Black and Pokemon White was Pokemon HeartGold and Pokemon SoulSilver. However, the newest Pokemon game to introduce new elements, areas, and Pokemon was Pokemon Diamond and Pearl.
just wait and do jobs for baoba the safari manager and eventurely u'll unlock some and if u do baoba will tell u this is in Pokemon soulsilver
Talk to EVERYBODY, sometimes there are secret houses or areas with people that will give them to you.
In Pokemon heart gold & soulsilver you must complete all the puzzle and have unlocked all the areas before you are able to get all the unknowns
You can't, but you can use it in the Final Maze and in other areas you may find legendary pokemon. I've heard rumors thats articuno, moltres, and zapdos live in the Final Maze and you can only get to them with the secret slab in your inventory. Other pokemon I don't know so you can google something like: "What Pokemon can you get with the Secret Slab"
no sorry the only ds gamwe to get trapinch in is pearl and i dont know about heartgold or soulsilver go to this website and go to pokedex www.serebii.com
After defeating Red, turn on your Radio on any Wednesday and tune to the Pokemon Music Channel. With the Hoenn Music on, walk through the grass in certain areas of the game and you may encounter a Plusle or Minun (or even other Hoenn Pokemon!).
