For a topper, I stuck 2 x coconuts on my Gilligans Island n a Bikini top sitting next to them (remember Gingers big tits from the show) with a Small Pineapple, n some shells, basically the things u collect when playing the game. Its packed up at the moment, cause I just moved, but it will be up n above soon.
Didn't kill any turtles, but a thick piece of rope etc all looked the part as a topper. Only thing I needed was a sea captains hat.
The stuff you have to feed to Kona-the Volcano is what I thought would be the best Topper stuff. Hope it helps.....
