A boy and his loyal dog, no? His loyal skeleton? He goes everywhere with Bones. 
Just in time for Halloween. I case there’s nothing wrong with it. But I think it may be time to introduce a pet that actually breathes into the boy’s life.
We found my toddler son sitting on the couch one morning with a (unopened!) jar of vinegar next to him (carried from the pantry, apparently). We figured it was his new friend “Vinnie.”
If the pet(s) start disappearing, then it’s time to really worry.
For awhile, our daughter’s favorite companion was a rubber skeleton about one foot tall that she called “Bones.” Lost interest when Bones’s leg broke off.
Some day that kid will learn that he has his own “best friend” inside himself.
Patton Oswalt on his daughter’s reaction to the skeleton inside her:
Especially if the kid starts asking for more and more vinegar. And a grown-up sized barrel to keep it in.
