Inazuma Eleven (2008)

Season 1: Episode 100

After Inazuma Japan's practice, Hiroto decides to go for a short run in a nearby forest, as he thinks his dribbling won't be able to break past the defense of their next opponent, Orpheus. Kogure, having been looked down by Hiroto and Kogure. Someoka earlier on, pulls a prank on the latter. He ends up being chased after by an angry Someoka, and runs into the same forest Hiroto is currently in. Hiroto runs into Kogure, and they encounter a kappa-looking boy, who wants an autograph from Hiroto. Both Hiroto and Kogure decide to camp out in the forest because they can't find a way back.
