Talking Dug Plush

The Disney Up Talking Dug Plush - 11" was an instant buy having seen Up. (The Scrooges selling Dug for twice the price on Amazon should be ashamed of themselves.) Suppose "Squirrel!" was too obscure for the toy, which appears to need surgery should its battery ever die. Wonder why they didn't just put the voice box in Dug's collar like the movie version?
