Query: smells very bad

I really wanted to like these, they are just adorable. I ordered two humidifiers (frog and penguin) and both had a strong odor right out of the box. They smell was very chemical like. I decided to give one of them a try to see if the smell would fade. I even washed the frog out with vinegar thinking it would help but after running it for two nights, all it did was make my child's room smell like chemicals. They are both being returned.
