The three-feet tall model will mark the launch of Mega's Thomas & Friends construction range.
The 3ft build will be on show around the theme park and also in the world’s largest Thomas store, alongside a large display table exhibiting the Mega range known as Thomas World.
Buildable characters and a two-in-one buildable Thomas that transforms into a train station are also on display in the discovery/education centre at Thomas Land, where kids can sample the products.
As part of an exclusive partnership with Thomas Land, during September and October, Mega Bloks is offering kids the chance to enter a competition to guess the number of bricks used to build the giant Thomas.
The competition winners will receive a selection of prizes including Mega Bloks products and VIP tickets to the Thomas & Friends 65th Birthday Christmas Bonanza.
The firm is also looking to brand one of the rides at the park.
Mary Price, UK and international commercial and marketing director at Mega Brands commented:
“We are extremely excited to have obtained the number one boys pre-school licence in the UK for our construction range and to be part of the drive to bring the Thomas brand to a whole new level during its anniversary year.
"Our work with Thomas Land takes our marketing campaign to new heights and we believe really shows our commitment to the success of the range."
Helen Pawley-Tuft, general manager of Drayton Manor Park added: "We are delighted to team up with the number one in the junior construction market.
"We have been able to work together to implement some very new and exciting marketing campaigns which will benefit both parties long term."
