I stop you right away! Do not expect these fishes to sing you lullabies to help you fall asleep… First of all you won’t hear anything and second of all, that’s certainly better that way.
Yes, they look cute, but their voice is terrible. They use ultrasounds to sing ultrasongs, which will scare away your most terrifying nightmares! Yes, they sing THAT badly. But hey, then you can really sleep like a baby. So kids, don’t be afraid anymore, with these fishes around, you’ll make the most beautiful dreams!
Ps: For people use to travel, it’s better not to bring the mobile on the plane. There’s no “airplane mode” button. And if someone is having nightmares, they will start singing… you might end up doing loops…
Ps2: For people living next to the sea, it’s better to put the mobile as far away from the window as possible. You don’t want to end up with a submarine in your garden.
