A Pokemon Mystery Dungeon Question?

Question

I beat Raquaza and i evoled myself to a Machoke, when i tried to evolve to Machamp it said i needed a special item? any1 no what it is?

Answer 1

you know when you talk to the 'voice' and it asks if you would like to use an item? that's not just for using stones, it's also for trade evolutions.

if you remember, in the main series, you need to trade a machoke to make it evolve into machamp

in pokemon mystery dungeon, you need to use an item called the link cables
