Using your ZURU Robo Fish is easy! Just drop it into water, and it will start swimming in up to 5 different directions and can move around in a space of up to 6ft. The water activates its special technology to bring it to life. There are 6 colors to collect, so try to get them all to complete your Robo aquarium. When it comes to dispatch, the styles are selected randomly. If you want a specific style, add a note to your order and we'll do our best to help based on what's available. Each fish is sold separately. If you really want to pick the one you like, head to your local Toyworld store. To keep your Robo Fish in good condition, make sure to dry it off after use and store it in a cool, dry place. Don't expose it to extreme temperatures or rough handling.
