Sasuke took another bite of the omusubi, trying to figure out how useful it would be: this was weird, to be sure, but far from debilitating. He supposed that it could be done to force people to taste blood or vomit -- or even less pleasant bodily fluids -- but what were the chances of taste alone bringing someone down, even if it came associated with some kind of memory?

"The genin probably won't be eating in the maze, either," he pointed out. "And if they were, they'd be the overconfident type that would be easy to fool."

The orange-flavoured rice texture was bizarre enough that his body cooperated, too, and it didn't take long before he'd isolated the point of intrusion and flushed it with his own chakra, restoring the proper flow.
