Workers at a drinks stall rescued the 2.5-metre (8-foot) tall model with a yellow head and blue torso.
"We saw something bobbing about in the sea and we decided to take it out of the water," said a stall worker. "It was a life-sized Lego toy."A woman nearby added: "I saw the Lego toy floating towards the beach from the direction of England."
The toy was later placed in front of the drinks stall.
