Before we start, it's important to note that Chihuahuas can develop food allergies at any stage in their life. Even if they've eaten the same type of name brand dog food for years, their body chemistry could change all of a sudden, causing them to experience an allergic reaction from it.
The crew also filmed many scenes in the north of Vietnam, as well as Oahu, Hawaii. No doubt the shots of Vietnam's tangled jungles helped to establish Skull Island's authentic 1970s feel. Check out the island for yourself in the trailer for Kong: Skull Island:
In the southwestern corner on the docks, you'll see a strange statue next to a ruined house. Read the inscription, then enter the house. Inside, you'll be attacked by a skull warrior (6th-level undead/4th-level fighter). When it's dead, take its head and place it on the altar to open the seal to the first level.
