Seeing how desperate Naruto wanted to find Sasuke, Team 8 came up with a solution. They requested Tsunade assign them a mission to find the legendary bikōchū beetle that could track any target as long as it had the target's scent. As Kurenai was still hospitalised and there were no other missions available, she approved their request. Naruto was placed on the team as well after being caught spying, and forced to vow not to continue asking for missions to be sent to search for Sasuke, if this one failed. Naruto was annoyed, however to be under Shino's command. Upon finally arriving at the nesting grounds of the bikōchū, the team had great difficulty searching for the bikōchū.
