What happened to that part in Bolt?...

That part was only on the Bolt trailer/commercial and that is not the only line they took out also they took out when Bolt jumps out of the trailer and runs in the hallway someone yells out "stop him he hasn't been off the set before" and also when Bolts in New York someone says "The televisión hit mostrar Bolt has been shutdown when their estrella dog has gone missing"

It was never used!

Reason: Bolt doesn't know what the navy is, so they didn't use it

It is a deleted scene from the movie. It is in the Bolt book novel but they never used it sorta like the one that when Bolt was dragging Mittens around NY, a little girl asked her mom this: "Mommy, is grandma a robot?" Mom- "No honey" Girl- "Is chocolate cake healthy?" Mom- "No honey" Girl-" Do doggies walk kitties?" Mom "No honey"
That is in the book, (the novel) If tu don't belive me look it up in the novel.
