It's called "The Monster" -and for three days over the upcoming long weekend, what is officially the world's largest inflatable bouncy castle (so big it's for for adults only), will be setting up its home in Melbourne Showgrounds.
"With over 270 metres of madness, the inflatable obstacle course is the ultimate bouncy castle experience for adults," the fine folks behind this gift to the world say.
"Participants will be able to run, jump and boogie their way around the phenomenal 30 obstacles, before grabbing a beer and a burger and dancing the day away."
