As instructed by old Mr. Hanalei, Greg, Peter and Bobby go to the ancient burial caves to return what they believe is the bad luck tiki idol to appease the Hawaiian gods. The boys are in for a bit more potential bad luck as they are unaware that they are being shadowed by a mysterious and solitary man, who will resort to anything to get rid of the boys so that they can't or won't report what they've seen in the caves. Meanwhile the girls, who know what the boys are up to, have to decide what to do when the boys are gone longer than they should have been. Once Mike and Carol find out what's happened, they have to find out where the caves are hopefully to find a safe Greg, Peter and Bobby.

While in bed, Peter sees the tarantula on top of his pajama tops. He says "Get it off me!" showing a close up of his face on his pillow. The shot goes to a close up of the tarantula and then back to Peter's head, but his hair is slightly different (slightly longer/bushier) and the pillow does not have the same creases on it. Also the lighting of the shot is slightly darker. See more
