Naruto's copy also accidentally bumped into Sakura, who was walking out of the library with an extremely tall stack of books.
The group outwits and defeats their copies except Naruto, who uses Nine-Tails' chakra fuelled shadow clones to defeat his copy, because his copy was running up a huge debt under his name, and ate all his food (including some ramen he was saving for a special occasion). After realising that Naruto and Kiba argue too often while Hinata worries for the others too much, they head into the town to stop their copies. Working together, the group escapes from the cave-in with the treasure, but learns that Hinata injured her leg.
'Run, Dodge, Zigzag! Chase or Be Chased!' (疾走、迷走、ジグザグ走!追って追われて間違えて, Shissō, Meisō, Jiguzagusō! Otte Owarete Machigaete) is episode 176 of the original Naruto anime.
