The nearly 21-metre-long replica of the water mammal – named  – is the latest project of Dutch artist Florentijn Hofman. The fun sculpture was commissioned by the Thames Festival Trust, which had approached Hofma to design artwork for Totally Thames, an annual festival celebrating the river. 
The giant hippo – which is a follow up to his famous inflatable duck – was manufactured in East London's Royal Docks using wood paneling throughout and is now anchored at Nine Elms on the South Bank in London, remaining there until September 28 when the Totally Thames celebration comes to an end. 
“I wanted to use the hippo to get people out of their homes, away from the Internet and the TV, and to explore London with a new perspective,” Hofman said of his new piece.
