Thanks to walk through, I didn't check the bed for a clue paper. Despite the fact that I had read the word pairs, I didn't know they were related to the anagram puzzle which provided more than enough words to solve it. Also, the buttons didn't flash every time I clicked them. I decided to ignore it and kept clicking. Finally, I received a candy bar.
Overall, I think each of the four episodes is loosely connected to one another. :|
