Ocquarium is a replica of the Android™ Oreo Easter Egg, which has been backported as a standalone application for Android Lollipop devices and newer. It is a free-to-use application developed by EAZY Code and is available on the Google Play Store. It works seamlessly on Android Oreo as well.

The app’s main attraction is the friendly octopus that can be played with by tapping and dragging, or simply watching it float around on the screen. Ocquarium can also be set as a live wallpaper or a screensaver, which is an added bonus for users who like to customize their device.
