Where did Annie gone? Hiding hiding hiding hiding.

Puppy: Annie! Annie! He [I] lost my Annie. Annie sad. Puppy lost it. He [I am] missing Annie! Annie gone...

few minutes later, denial:
Puppy: (pointing to a truck behind Clarabel): It's Annie!

...few minutes later to a tune of "Little Red Caboose"
Puppy: Where did Annie gone? Where did Annie gone? Hiding hiding hiding hiding.

Annie & Clarabel are two coaches from Thomas and Friends. They are identical but somehow he knew he was missing Annie and not Clarabel. I thought it was funny how he was dealing with his loss:

1. he's devastated
2. he substitutes his loss with an alike item 
3. he ponders about it.
