The toolkit, the Bamzooki Zook Kit, enables users to build virtual creatures, Zooks, and test them in a real time physically simulated environment. Kids used this software to build Zooks which were submitted to the BBC. Teams were selected and invited into the studio to enter their Zooks in various contests. The new series 'Bamzooki: Street Rules' which aired in November 2009 features fully interactive contests, where the participants direct their Zooks by shouting instructions as well as contests set on the streets and rooftops. 36 teams were selected to take part in the championships, with 9 heats, a semi final, and a final.
