A × Dangerous × Watchdog

After arriving in the Republic of Podokea, Gon, Leorio, and Kurapika board a tour bus to Kukuroo Mountain, where Killua lives. However, they're blocked by a massive "Testing Gate." Anyone who attempts to enter through the side door is eaten by Mike, the watchdog. Gon tells Zebro, the elderly gatekeeper, that they are friends of Killua and asks to be let in. Kurapika eventually realizes the front gate is not locked, unlike the smaller side gate, and Leorio struggles to open the gate. Zebro eventually explains that each door of the gate weighs two tons, the minimum amount of strength required for opening just one door. (The group learns that Killua opened three levels of doors, sixteen tons total.) After arguing with the family butler and attempting to climb over the gate with his fishing pole, Gon's spirit convinces Zebro to open the Testing Gate and accompany them so they can enter without Mike eating them.
