The Hedgehog (ヘッジホッグ) is a First Stage obstacle that was introduced in SASUKE 29. It's a replica of the Rolling Saboten from DOORS. The competitor must cross a 4m long rotating log that has several large pillars to slow down movement. Due to safety reason, competitors are not allow to grab the pillars albeit that the log will usually stop rotating if competitors were stuck on the log, leaving with the fact that competitors have failed the obstacle. It was replaced with the Orugōru in SASUKE 31.
