I went to the Big Pineapple a few times. It used to have a park there with an animal nursery and other attractions which were fun. I have dim recollections of also visiting the Big Cow and the Big Prawn as a kid. The House of Bottles was pretty cool. It had a big beer bottle with a slide inside which appealed to nine year old me.
I've seen the Big Pineapple, and the Big Banana and that's me at the Big Chair in Broken Hill. I've driven past the Big Koala at Dadswells Bridge in Victoria more times than I care to remember. I love the "big" things.
