Batteries left in toys for prolonged times can breakdown and corrode the battery pack. The rusty liquid created leaves a telltale orange stain on fabrics and around the battery pack. By the time you notice the stain the contacts within the pack are usually beyond repair but the toy is salvageable if you follow this guide. The reason this guide opens the entire toy is that it was impossible to tell what the function of any wire had before it had corroded from the battery contacts. (And the wires were not the usual red, black and white)
