Kids will be able to create train track effects on the mat by using the Thomas roller.

Thomas & Friends is expanding its product offering with the new Aquadoodle from TOMY.

The new item, known previously as the Aquadraw, lets children create train track effects with its Thomas roller and the easy grip pen.

By soaking the water tray, kids can place the Thomas roller over the pad and run Thomas over the mat to see the tracks appear.

Zoë Knight-Smith, associate licensing manager consumer products EuRoMEA at Mattel and HiT Brands, said: “We are delighted to be working with TOMY to launch this key arts and crafts item from Thomas & Friends, and look forward to developing our partnership further in the future by extending the Aquadoodle product range.”

The Aquadoodle will be available in various retailers including Argos, Smyths and Toys R Us.
