It was the roll of a lifetime.

Hundreds of amateur sushi chefs at the University of California, Berkeley got their hands fishy Sunday as they assembled a 330-foot California roll.

A university spokeswoman says Sunday's rice-and-seaweed monstrosity is the largest of its kind ever rolled, surpassing a 300-foot California roll made in Hawaii in 2001.

Students used 200 pounds of rice, 80 pounds of avocado, 80 pounds of cucumber and 180 pounds of fish. And in a nod to the school's scores of vegetarians, the final 15 feet contained tofu instead of seafood.

Members of the Japanese Graduate & Researchers Society dressed as ninjas started the giant project.

The stunt was part of celebrations for the 50th anniversary of the school's Center for Japanese Studies.
