Question: Given the following context:  Barbie stars as Genevieve, one of twelve princesses who live in a castle with their widowed father, King Randolph. The princesses have adventurous and free-spirited natures that are viewed as "unladylike" and "non-proper" by other members of the royal society. This leads King Randolph to summon his cousin, Duchess Rowena, to the castle to help raise the princesses. Unbeknownst to King Randolph, Rowena plans to poison him and get rid of his daughters so that she can become queen. Attempting to break the princesses' spirits, Rowena makes their lives miserable by stripping the castle of everything they love,  making them wear grey dresses and banishing singing and dancing. The princesses find comfort in their late mother's favorite story, which tells of a magical kingdom where golden flowers grant wishes and princesses can dance at an enchanted pavilion for three nights. The princesses realize that the story contains clues on how to enter the magical kingdom from their own bedroom, by dancing on specific stones on the floor from oldest to youngest. Now inside the magical kingdom, the princesses discover that the water there possesses healing properties. The next day, the princesses appear tired and the duchess finds their new dancing shoes worn through, arousing her suspicion. The royal cobbler and Genevieve's love interest, Derek, comes to fix their shoes and sees that they are covered in gold dust. When King Randolph mysteriously falls ill, Genevieve is prompted to ask Derek to investigate Rowena's true intentions. That night, the princesses return to the magical kingdom to dance. During this time, Derek discovers that Rowena is stealing heirlooms from the castle and dealing with an apothecary, and he rushes back to the castle.  answer the following question:  Who is planned to be poisoned?
Answer:
King Randolph
