There are 7 collectibles in the Pasta Collection and here is their names and how to get them:
– Conchiglie: from doing the Silence Don Romo Jobs
– Farfalle: from doing the Silence Don Romo Jobs
– Lasagna: from fighting
– Manicotti: from fighting
– Rotini: from jobs (any job, any city)
– Spaghetti: from jobs (any job, any city)
– Ziti – free gift from Mafia members
If you manage to find all these items in time (for me, the hardest to get are the Rotini and Spaghetti), you can trade in the Pasta Collection for a really cool reward: the Home Cooked Meal, which gives 18 Attack and 68 Defense.
Good luck completing the Pasta Collection in Mafia Wars!
