Currently I am unaware of any outlets which sell Aquaroids in Europe, I am considering selling them through my site in the near future once public awareness and demand for Aquaroids increases. If you know of anywhere that does sell Aquaroids in Europe, specifically in the UK please let me know at info@aquaroid.co.uk
The site has been updated but is still sparse on info as I'm trying to compile as much as I can find however there is still very little out there on the internet.

About the size of a large grapefruit, the robot jellyfish gently moves up and down its tank when the aquarium lights are turned on. Thanks to sensors, it doesn't touch the sides.
Powered by penlight batteries, the pets cost 6,000 yen (US $50). They swim gently around the aquarium until they run into the side wall or another creature, when a nose-mounted sensor turns them around and they gently move off in the other direction. The jellyfish move by magnets and are sensitive to sound, reacting to a microphone attatchment

Users say watching the jellyfish can be as hypnotic as staring at the real things.

"Observing the gentle rhythms of the jellyfish has a 'healing' effect," Terumi Endo, a spokeswoman for the toymaker, told the London Times. "Research shows it is good for soothing nerves and alleviating stress." According to The Times, the jellyfish was a big hit with stressed-out workers who "spend hours staring into the glass tank that houses the creature."
