Per Pex on the official forums, the Cloudy With a Chance of Meatballs promotion will be drawing to a close "on or slightly after September 30th". That means that if you have lots of meatballs, vegetables and fruits to turn in to Helga in Sanctuary, now is the time!

The decision on whether or not the ingredients for the Spaghetti with Meatballs recipe will be available after the event is still pending. ZAM will keep you updated as soon as we find out the scoop.
