There is a Clifford episode where Clifford and friends dig up dinosaur bones, and once the dinosaur is all set up, they all stand in front of it for a picture. Someone says, “Say ‘dinosaur’!” and they snap the picture.
Mara loves re-enacting major sections of Clifford episodes, and Daniel found Mara after her nap, having lined up all her animals
(Left to Right): Perkle Bear, Puppy Dog, Pink Bear, Ballerina, Yellow Bear, My Little Lucy, and Blue Bear.
Mara was saying, “Say ‘dine-a-door’!” and then laughing hysterically. 
She thought she was pretty funny! (And quite frankly, we did too!)
