Cube Escape: BirthdayEdit
She is seen sitting by Dale's birthday cake and present. She only asks for the player to check the mail, which has a letter addressed to Dale from Mr. Owl. If she is given a piece of gum, she blows a big bubble that can be popped with a sharp object. The pre-chewed gum is then taken and used later to catch a fly for a mousetrap. When Mr. and Mrs. Vandermeer begin to sing "Happy Birthday", they are suddenly stopped by the doorbell ringing. Mr. Rabbit breaks into the house, and shoots her dead.
With time reversed back by the blue cube, Mrs. Vandermeer is brought back to life, but with no recollection of the past events. When Mr. Rabbit returns to break the door down, he is shot by Dale's grandfather. Afterwards, she and her husband cower in the corner, and she can only say, "Dale, what happened today?".
Cube Escape: ParadoxEdit
When the player has their past mind, they are taken back to their childhood birthday. She asks the player to prepare the decorations, and then call the magician, Mr. Eilander. After he arrives, he hides around the room, and Mrs. Vandermeer gives hints as to where he is hiding. Eventually, she asks the player to open their present, where Mr. Eilander pops out and uses his hands as guns to shoot her and her husband dead.
