Crumpit and wants to tell The Grinch about Christmas.
She's played by two little girls every Winter at the Olde Globe in San Diego.
Martha turns down May Who's proposal and decides that she would rather stay with the Grinch instead.
The Grinch, sensing innocence in the young girl, covers up his theft by fibbing to her, saying that there is a broken light on the tree and that he was taking it to his workshop to fix the problem and then return it on Christmas Day when she wakes up.
She first appears in It's The Thought, Who Likes Christmas, I Hate Christmas Eve and Whatchamo.
