It looks like a cake. That is, if you're familiar with cakes stuffed with rice and meat and wrapped in seaweed. The oversized musubi pictured above is known as the Stan-Musubi, named after the owner of Ola's Hawaiian BBQ in Fullerton.
The disclaimer I signed before taking the challenge in November 2011 listed the big musubi at over 7 lbs. It's got a ton of rice, which I usually don't handle well. Inside the rice you'll find chicken and beef. You get 35 minutes to eat your way to a free meal.
A group of us went together (names withheld to protect the guilty). It took the kitchen awhile to prepare all the food, but it was honestly delicious. This is a challenge that I'd do over if I could. Free food rocks, but awesome food is a step above.
From musubis, the night led us to a very non-food based situation complete with laughter and arm wrestling.
It's not clear to me how to follow up a story like arm wrestling. At least no one was seriously hurt.. a classmate from high school refused to arm wrestle me because of all the horror stories he heard associated with the activity.
