The current Tumble Bug & Spider at Luna Park Sydney are different to rides of the same name that I recall being there from the 1960's. The Spider was more like what used to be known as the Octopus and the Tumble Bug was what I think is called a switchback railway. These along with the Flying Saucer and Calypso rides were removed sometime during the 70's. According to the book Luna Park Just For Fun, the Calypso was destroyed by fire while in storage.

The Calypso got sold at the auctionin the early 80s i think it was, Watkins brought the super Jet, Pig Train, and Calypso all from luna park. It now sits at there yard i see it quite often actually i might get some photos of it one day. But it most definetly did not get lost in a fire.
