Taco Bell Chihuahua, Set of 4, Collectable , Need new Batteries But Easy Fix

Set of 4 Taco Bell chihuahua dogs. As pictured. They do need new batteries. I have been told the compartment is close to the surface and a skilled restorer of plushies can fix them easily. No stains or spots. Stored since the 90’s in climate control. They are really cute restored or not.
