Cookie Freeman ("Aunt Cookie" to Huey and Riley Freeman) is the sister of Robert Freeman. Little is known about Cookie, other than that she once gave Riley a necklace for Christmas; not the chain he wanted, to his dismay. She was the one who informed Granddad about the death of his former friend, Moe Jackson, and accompanied him on the party boat where Moe had requested his funeral to be held. She tries to help Robert to let go of the past and come to terms with Moe's death. She is successful, but not before Moe plays one final prank on his old friend.
