Review on Barbie Dreamtopia Rainbow Lights Mermaid by Osoulo Sharp

Must be a serious issue as some people's mermaids seem to last months but mine, like others, only lasts a few weeks. A total of 4 times in the bath and it stopped working. I took off the battery cover and it's all wet and rusty. There is an o-ring inside, but it's pushed so deep into the crack that I don't think it actually does anything. I ordered new batteries (I needed that size for another toy anyway) so let's see what happens. I will add some waterproof tape to form a seal. It might work again but based on other reviews I doubt it. Luckily my 3.5 year old still enjoys playing with it. However, at $20, this is an expensive Barbie doll that doesn't perform as advertised. I'm grateful it wasn't a gift.
