You can buy Thomas the Tank Engine wall decals from First Years in 1 Utama. But it costs an absolute bomb. I can't recall the exact price but I think it was RM100+. It looked really nice though, it was a large mural and I know Connor would have loved it.
Happily, I've found an alternative that is much friendlier on the wallet. I did a Google search and found a company here in Malaysia that sells them for a mere RM52. The wall decals are imported from Korea. I placed an order right away because Connor's fascination with Thomas is now bordering on obsession. I'm now praying and praying that they come looking like Thomas, not like some ciplak Thomas with the face looking not quite right.
You can order the wall decals here.
