Every now and then it will hold a lucky egg.
The women will give you the item "Lucky Punch", it is a held item that only effects Chansey and Chansey only. It boosts the Critical Strike ratio of Chansey my a significant amount. It is in all honesty a useless item as Chansey's attacking stats are extremely low and only really used as a tank in competitive play. In the previous versions, the lady use to trade you an Aerodactyl for the Chansey, but has since been taken out of the game making it basically useless to show her a Chansey.
you can't unless you trade it from another game.
Wild Chansey can sometimes hold that item to find Chansey go to the safari zone.
The item Lucky Egg, that doubles the Exp.Points earned in battle, can be obtained by catching a Chansey in the Safari Zone. You will have to be lucky though, since there is not really that high percentage of getting a lucky egg with the Chansey you catch (and it is not easy to meet a chansey, nor catch it, either...). As a sidenote, I actually got lucky as hell and receive a lucky egg on the third Chansey I ever caught in Firered. If I forgot to mention it, the Chansey will be HOLDING the item, in case you are lucky enought to catch a chansey with it.
Do you mean what is an oval stone? Well, an oval stone is an item that when held by a Happiny during the Daytime and leveling it up evolves it into Chansey.
A lucky egg in Pokemon diamond/pearl is an item held by wild chansey. they apear exclusively in the grassy areas of route 209 and 210. every chansey you encounter has a 30% chance of holding an oval stone a 5% chance of holding a lucky egg and 65% chance of holding nothing. the best way to get the lucky egg is by entering a Pokemon chain on chansey with the poke radar, and having a Pokemon with the ability "frisk" as your lead Pokemon. this will tell you if the chansey is holding the desired item. then you either use a Pokemon that knows pluck to steal it or you capture the chansey.
It evolves when it's very happy. Not at a certain level. Ways to make Chansey happy: Catch Chansey with a Luxury Ball Use a Joy Scent on it Carry it in your party Give it a hold item that fosters friendship
The lucky egg is an item that doubles the amount of exp that a Pokemon gives. You can get it from a Chansey if you are lucky (found near Solaceon town).
If you catch a wild Chansey there is a 5% chance it will be holding a Lucky Egg. I recommend using the move thief to steal the Chansey's item instead of catching it. Since Chansey is VERY rare you probably won't find him unless there is a swarm. Patience is key good luck, no pun intended.
The Oval Stone is an item in the Pokemon games which can be used to evolve certain Pokemon. For example, it can evolve Chansey.
Pretty much all you can do is catch a chansey and hope that it's holding a lucky egg. :P
No. Chansey is 100% female.
