South Dunedin Street Art Trail artist Koryu Aoshima always had the extension to the Cameron St mural in his mind.
He did not know what the additional details would be but had an idea to extend the KiwiRail train featured in the mural.
The original Cameron St mural of a train with a Chinese lion at its head recalled the Asian community that helped build South Dunedin out of what once were wetlands.
The addition to the mural depicts an extended train passing St Clair Beach with members of a Scottish marching band riding a lion, sea lion, unicorn and albatross alongside it.
Mr Aoshima said the additional details were a nod to Dunedin’s Scottish heritage.
Street Art Trail co-founder Rachel Elder said the mural showed the peninsula and Otago’s earliest settlers, Ngai Tahu arriving.
She said they had a village at the Otakau Marae at the mouth of the harbour and when the Scottish settlers arrived in 1848 they were looked after by Ngai Tahu.
The other Street Art Trail co-founder Claire Rye said the bizarre details of the mural gave it a dream-like appearance.
"It’s a big Ōtepoti dream.
"It makes me happy looking at it."
