You can get a Pokemon very happy by treating it well. Never let it faint in battle or repeatedly let its health get red. Your rival's sister can also evaluate happiness and groom the Pokemon to make it happier (but only after you beat the Elite Four). The most expensive way is to give your Pokemon vitamins, but it works the best. When some Pokemon are really happy, they'll evolve. Good luck!
riolu evolves when he is really happy
Go to the little house in the north side of goldenrod and she will say a sentence on how happy your Pokemon is, if you want your eevee you want to here the lady say something by the lines of "your Pokemon really trusts you" or "your Pokemon is really happy!! you must be a good owner"
u need to make chansey really really happy then level it up once then it evoles
You need to make it really happy then use an oval stone on it, to evolve it into a chansey. Then, get it really happy again and it will evolve into a blissey. I'll tell you now, it's a really boring process... Jonsteph
In Pokemon heart gold you can get groudon later in the game but apart from that i really don't know. (sorry) PS happy hunting

You can make it happy by treating it to spa.
You can make it happy by training it a whole lot. usually it takes a Pokemon 20-30 LVs to be fully happy.
Really Really Happy was created in 2004.
you have to run around with it lots. also battle with it. those two things make Pokemon happy.
You have to get an eevee then make it really really happy then level it up during the day. If you level it up during the night, it will become an umbreon. p.s. its spelled espeon
The Oval stone evolves Happiny into Chansey.When Happiny is really happy, give it to her told hold then level her up by 1; she should evolve.If not then she's not happy enough.
