[Vanishing Act]

Instructions

The letters in the word at the top are slowly disappearing. Jumble the letters in the top row to get the clued word. For each line below it, the starred tile has turned into a new letter, and that letter will occupy that position for the rest of the puzzle. Keep up with the changes and solve the rest of the words.
