apparently it evolves with friendship
Togepi doesn't evolve by level. It evolves by Happiness.
Togepi doesn't evolve through level, but through Happines. I'd recommned giving it lots of proteins, calciums, and other medicines
when you trade a Pokemon in it becomes very hostile, try breeding another togepi out of it and training that one.
you need to battle with him a lot, and give him massages and calcium's
(this is how to evolve your togepi on Pokemon diamond or pearl) to get your togepi to evovle take it to the massage place in veilstone city and do it again the next day and feed it as many spicy poffins as possible! then look at the app number 20 and see if your togepi is on there if it is in second place or higher it will evolve at the next level! enjoy your togetic!
Togepi doesn't have a certain level for evolution; you need to have a strong bond with your Togepi, i.e. "happiness".
