A giant tortoise dancing in Animal Attic, disco moves in the Planetarium and ballet among the archives all make an appearance in Otago Museum's latest entry to the Great Museum Dance-Off.
About 20 staff showcased their quirkier side in the video, which has been released on YouTube along with entries from around New Zealand and overseas.
Voting in the contest, organised by the "When You Work At A Museum'' blog, began at 12am today and closes at midnight tonight.
Museum head of design Craig Scott said the video did not take long to put together and was shot over the course of about three days, before and after work.
"I guess it's kind of making museums seem like a really fun place to work.''
Veils, butterfly wings and animal suits were popular among staff who were shy about showing their faces.
Staff were free to do whatever moves they liked, he said.
"It's jumping around and having fun to the music.''
Otago chose a pop song this year, `Strangers' by Norwegian singer Sigrid.
Mr Scott said the museum entered the first two annual dance-offs in 2013 and 2014, but had to skip the following two.
Museum staff wanted to enter this one as it was the last one.
Initially they would be pitted against four other New Zealand museums, the South Canterbury Museum, the Air Force Museum of New Zealand, the New Zealand Rugby Museum and the National Army Museum Te Mata Toa, with the winner taking on other countries.
Otago had never been in the final and been narrowly beaten in other competitions by museums with a larger base of people, Mr Scott said.
"You can vote as many times as you want.
"Whoever had the most votes on social media got through.''
Traditionally the bulk of entries are from the US and Canada, but there are entries from around Australia, Mexico, and Eastern and Western Europe.
Mr Scott said the final would be on May 14.
