Sofia

"All I want for Christmas is my two front teeth. My two front teeth, just my two front teeth. Gee if I could only have my two front teeth. Then I could wish you 'Merry Christmas'!"

- Sofia singing "My Two Front Teeth" in the Christmas special.

Sofia is a member of the family and a non-canon cartoon counterpart to Macy, appearing in the Christmas Special "My Two Front Teeth".

Personality
Sofia is seen to be quite an animated and ambitious girl in the cabin. Similar to her mother Gloria, she shares her kind-heartened nature towards her family.

However, she is also somewhat too blinded by her innocence to detect when something has gone awry when confronting her deformed mother in the hallway (who she greets and eventually walks away).

Appearance
Sofia takes after Arthur by the matching ginger hair (put into the style of pig-tails) and green eyes. As well as sporting a cute red nose, red lips and a white onesie, she also seems to be missing her two front teeth (hence the name of the cartoon short).

Story
Within the beginning of "My Two Front Teeth", Sofia and Henry are seen shivering from the cold which prompts her to state "Well maybe you should get bundled up like a cute little Christmas present!" as she lifts up Ava bundled up in a blanket. Just when they are informed that dinner is ready, the doorbell rings to reveal Uncle Arthur at the door who greets her with a smile and a pencil and paper in-hand.

When questioned by him about what she wants for Christmas, she's unable to think of anything. Arthur suggests getting a larger mouth to taste more of her mother's great cooking. But - with his grin - Sofia settles on asking Santa for her two front teeth whilst singing "All I Want For Christmas Is My Two Front Teeth" by Donald Yetter Gardner.

After a brief jumpscare, the short continues with her handing Martin the Christmas list. It presumably takes place after dinner as Sofia is seen complaining about eating too much, leading to her stomach-ache as Gloria sends her to bed.

Once the cartoon returns back to Sofia on the 22nd of December, she exits her room to find a deformed version of Gloria standing afar. She tries talking to her only to receive no answer. Slightly disturbed and confused, she leaves for the living-room where she finds Henry and Arthur are waiting for her to bake some cookies (whilst Martin and Gloria get better). Arthur also stops to hand Sofia a gift made by Martin that she cannot open until Christmas morn.

As Arthur showcases the cookies to Sofia and Henry, each represent the family in this order: Henry, Sofia, Gloria?, Arthur and Martin. One cookie however seems horrifically burnt to a crisp, blackened and shriveled up. When Sofia comments about what happened to the cookie, Arthur briefly states "That one was imperfect-" before a jumpscare using the cartoon's introduction appears, ending the scene.

As the cartoon returns, the day ends like previously with Sofia complaining about how much she's eaten before being sent to bed in hopes of feeling better the next morning. This time it is by Arthur since Gloria is nowhere in sight.

On the 23rd of December, it shows Sofia and Henry in the living-room wondering where Arthur has gone. Just when he suggests that they should go look for him, camera footage of a room filled with Magical Sofia dolls appears instead. During the night of this particular day, Gloria can be seen entering Sofia's room before the next day plays out.

On the 24th of December, Sofia wakes up to hear Ava crying in the distance, prompting her to leave her room to try and find her. As she does so, disturbing imagery of the setting plays along with organ music from a nearby item. In fear, she calls out to her other family members in hopes someone might answer her.

Sofia enters one room in particular which is completely devoid of any light as the door closes behind her. Gloria indistinctly appears in-front of her as she calls out "Mama?" attempting to get a response. However, when the view sharpens, Sofia exclaims "You're not my Mama!" before pounding the door trying to leave, screaming at the figure to leave her alone whilst loud music plays in the background. She seems to calm herself briefly as a deformed version of Martin appears to which she asks "Daddy?" as the scene abruptly ends.

A scene involving Sofia The Singing Marionette plays out as she is strapped onto a chair, squirming and riving in an attempt to escape her restrains. After this, a grotesque image of Sofia's sunken eyes and broken jaw emerges. One last snowman is seen added to the collection. This time - however - they are covered with blood and their faces are censored. The cartoon's credits roll with Ava's decaying boy placed in Sofia's gift on Christmas morning.

Trivia

 * It's not entirely known why Sofia reacted differently when encountering her father than she did her mother if both share a deformed appearance.
 * In this cartoon short, she was the last victim of Martin (as Ava was killed after Gloria but only shown at the end of the cartoon).
 * Images/footage of her toy counterpart can be seen in this Christmas special more so than Henry.
 * Many comments of the original videos have taken time to praise Sofia's voice-actor for her impressive expression/tone during the more intense parts of the cartoon.
 * Sofia - unintentionally - makes a reference to Ava's demise and reveal within the very first lines of the cartoon when stating Henry should get bundled up like a cute little Christmas present before lifting up Ava. From that point, she is never seen again until the end where her remains are placed in a Christmas present.
