You can find heaps of Outrigger Island materials in the internet. Go to:
1) YouTube and search for "Outrigger Island" and you'll find heaps including self-made promotion videos from other churches or click on http://www.youtube.com/results?search_query=outrigger+island&search_type=&aq=-1&oq=
2) Go to the Lifeway VBS site at http://vbs.lifeway.com/vbs2008/yourvbs/
3) Guess who else in Malaysia is doing the Outrigger Island ... one of them is http://www.gbcpg.org/outriggerisland_flyer.htm
Hope you'll have a fun time surfing for ideas!
