A crew of fishing vessel Crystal Sea sent the project a photo of the mass of Lego pieces they had hauled up from the seabed 20 miles (32km) off the Cornish coast during the summer.
The haul included two yellow life rafts, two of the 28,700 lost overboard from the Tokio Express.
Also fishing off the Cornish coast, another fisherman found a grey Lego panel caught in his nets, a piece that had never been reported before and one of 6,600 lost at sea.
Ms Williams said fishermen and women tended to find the larger plastic items in their nets such as door frames, windows and life rafts, while beachcombers were more likely to find lighter pieces like cutlasses, life jackets and spear guns.
She said no Lego magic wands, dragon wings or witches’ hats lost from the ship had yet been reported to have been found.
