Dunedin artist Elizabeth Manson was underneath the blue horse head made of mesh, and while her show could have appeared lighthearted, she was protesting to drive home an important message.
No Show4 The Cameltoe No Show will have Ms Mason cycling around the hospital site in the bike lane for two hours every day of the 10-day festival.
She aims to shed light on her personal experience within the mental health system.
The cycling represented her experience of "going around in circles" and doing something that may be considered "crazy" represented the stigma around mental health, she said.
"It has taken me years to work out what happened to me and why it happened to me."
Early on, she was diagnosed as dependent on the health system, she said.
"When I asked for help that was seen as a symptom.
"The more I asked for help, the more they blocked me from help — If somebody is being asked for help, it needs to be looked into."
Eight years later, she received an apology from a community mental health centre, a letter that has featured in her previous three Fringe shows.
"Will it make a difference, or will I just get cameltoe?" she said.
