While the team are on their way to the Sparticle Project, Ami is captured in the woods by the Water Rats - a group who love life messing around on the river. The Water Rats are at war with the Menaces - and the Questers, persuaded by Ami, decide to help. Will Ami swap the seriousness of the Quest for a kid's life of fun and games? Jeffrey is keen to help out more, but his wheelchair needs more power. Tia and Jeffrey discover a satellite communication system which allows them to send a message into the ether, asking anyone out there for the batteries Jeffrey needs. They arrive back at the hotel to a package - it's from Anita at the university and it comes with a message.
