I have to know first which pokemon game are you talking about. Edit the category so that I can see and then I can answer.
it will need about 100 happiness
You evolve Togepi by Level up with Happiness at 220 or higher. You can't te;ll how many happiness your pokemon has though.
For a togepi to evolve you need to give it 220 happiness
max out its happiness
ok so you have to get the happiness up then it evolves into togetic then if u give it a shiny stone it evolves into togekiss
You'll have to make Togepi happy to high happiness/friendship.
In Pokémon games, Togepi's happiness level can be assessed by talking to specific NPCs, such as the Happiness Checker in places like Goldenrod City. These characters will provide feedback on Togepi's happiness, indicating if it is high or if it needs more care. Additionally, actions like leveling up, using items, and keeping Togepi in your party can increase its happiness. Once Togepi's happiness is sufficiently high, it can evolve into Togetic.
Togepi doesn't have a certain level for evolution; you need to have a strong bond with your Togepi, i.e. "happiness".
Togepi only evolves with love and happiness. If you make it very happy, it will evolve.
evolve togepi with happiness
Togepi, in any game, only evolves by maxing out it's happiness.
You must first get Togepi on route 230 using your poke-radar. Then you must get Togepi to evolve into Togetic. Togepi is a happiness evolution, which makes sense as Togepi is a egg Pokemon.
