See what this mother discovered as she went to put a new battery in her children's favorite toy.

It's one of Fisher Price's best sellers, and it's on Amazon's top five list of popular children's toys as well, but when a mother went to put a new battery in her son's Soothe and Glow Sea Horse, she was shocked and concerned by the melted plastic and very, very warm batteries that she found. There was also the smell of something burning as she got deeper into the insides of the toy.

And she's not the only one.
