What is hidden in 3D image?

The boss wondered why one of his most valued employees was absent, but had not phoned in. Needing to have an urgent work problem resolved, he dialed the employee's home phone number and was greeted by a child's whispered, "Hello."
"Is your Daddy home?" he asked.
"Yes," whispered the small voice.
"May I talk with him?"
The child whispered, "No."
Surprised and wanting to talk with an adult, the boss asked, "Is your Mommy there?"
"Yes."
"May I talk with her?"
Again the small voice whispered, "No."
Hoping there was someone with whom he could leave a message, the boss asked, "Is anyone else there?"
"Yes," whispered the child, "a policeman."
Wondering what a cop would be doing at his employee's home, the boss asked, "May I speak with the policeman?"
"No, he's busy," whispered the child.
"Busy doing what?"
"Talking to Mommy and Daddy and the Fireman," came the whispered answer.
Growing more worried as he heard a loud noise through the earpiece on the phone, the boss asked, "What is that noise?"
"A helicopter," answered the whispering voice.
"What is going on there?" demanded the boss, now truly apprehensive.
Again, whispering, the child answered, "The search team just landed a helicopter."
Alarmed, confused, and a little frustrated, the boss asked, "What are they searching for?"
Still whispering, the young voice replied with a muffled giggle..."Me!"
