 * Rachel Parham

Rachel's birthday
Rebecca wrote her sister, Rachel, a poem with a secret code to help her figure out what 5-letter word unlocks the puzzle pod. The items were basically a gift for her which was given on her birthday. She liked it, and she eventually figured it out, but Rebecca got impatient, giving her a hint, so that she could open it on her birthday.

Answer
Most people claim that the answer is "Mabel". However, that is the wrong answer. The real answer is "dolls." In the poem, she said Mabel's name was a key and that the viewer needed to remember this phrase. Those are the two most important aspects of solving this riddle. The alphabetic numbers of the letters in Mabel are 13, 1, 2, 5 and 12. And if they go to the 13th, 1st, 2nd, 5th and 12th letters in this special phrase, they spell out the word "dolls."

Reception
The reception for this video was positive.
