We must recognize that this toy meets the main function: blowing bubbles in the bath. A small bottle of "bubble product" comes with the toy and lets you fill the tank and is in the octopus mask tube. The dosage is random (to ajouster because it does not work every time) and if you want to remove the octopus from the bath each time, the bubble produced tank will fall over and you will lose your small reserve. Be aware that the bubbles are produced by a small blade that rotates and a fan. But this fan really makes a lot of noise, and the blade rotates slowly, so that the bubbles are not very numerous. Side activities, like every Vtech toys octopus offers very friendly songs, with large buttons and lights. The only downside is that the buttons are a bit hard to push for smaller (my daughter is 1 year).
