But, in winning the prize, Mr Grant had to overcome a major setback – his original design of a single mammoth was targeted by arsonists and destroyed.
The mammoth threesome which rose from the ashes was completed with the help of Mr Grant’s family and people from the local community who pitched in.
Weetabix chief executive Ken Wood said the judges had been impressed by the sheer originality and effort from the entrants.
“The sculpture of the family of mammoths really stood out, capturing the spirit of the competition perfectly,” said Mr Wood.
There were 10 regional winners who competed for the overall prize. Designs included a teddy bear, a lion, the Loch Ness Monster and Noah’s Ark.
