With millions of dollars worth of rides and thousands of animals on display, the Royal Easter Show held in Sydney, Australia, every year is a big deal for the locals. But not all the visitors are cute and fluffy. The Robosaurus, which took 30 firms two years to build, will breathe fire and "eat" cars twice a day during the two-week event. The electrical and mechanical monster, originally from the US, is around five storeys tall and weighs 27 tons -- three times as heavy as a real Tyrannosaurus Rex.
