Whats Pofin?
Poffin is the Pokeblock of Sinnoh. So, like Pokeblock, it ups your Pokemon's condition depending on what Pofin you give it. And again, depending on your Pokemon's Nature, decides what type of Pofin your Pokemon likes and what it hates. Give your Pokemon Poffins to make them better in Contests!
Blending
Once you have a Poffin Case and a berry, go to the House south of the Pokemon Center in Hearthome City. When you go inside, you will see a machine on your left and a girl under it. Talk to her. She will ask you if you wish to make some Poffins in a group or by yourself. Chose with one you want. Then chose a berry out of your bag. You will put it into a blender. On the touch secne on the DS, move your stylus cloclwise or anti-clockwise depending what what the DS shows you. You may make it fast or slow. But if you go too fast it will overflow, and if you go to slow, you will burn it and make your Poffin less effective.
The Result
After around a minute of cooking, you stop cooking. You will see a card that says how long you were making it, how many times you overflowed, and how many times you burned it. It will say what kind of Poffin it is and it's smootheness. After this you wll be asked to make another one or not. Chose which one you want. If no, the girl will say come again and now you may give your Pokemon the Poffin!
