In the middle of their spar, Naruto is too busy preparing a rasengan to notice his opponent Kiba slip behind him. The dog boy produces an unassuming wooden jar and unscrews the cap. He's been looking for an opportunity to use the bugs he'd swiped from Shino's apartment, and now one has presented itself. In a practiced technique, the cheeky shenobi snags his opponent's undies and upturns the jar, dumping the contents down Naruto's briefs.
