The Secret of Psychic Bigfoot

The team gets there and they find Buck act in weird. Is he in a psychic Bigfoot trance again? See, I don't feel like that would be a good arc for him. He's waiting to do the big Scooby-Doo mystery wrap up speech. It turns out Buck was saved and escaped psychic Bigfoot mastery because of a word that Cherokee girl kept whispering. Adavansi. What does the word mean? What was the secret of psychic Bigfoot? Hand job. Just really wanted a hand job.
