Here is my MOC of that cheeky little engine Thomas. Peep! Peep!
Now, below are some more pictures of Thomas as I would have him in a LEGO set. Of course, his wheels would need to be blue, and his superheater above his boiler would need to be blue as well. The LEGO Company would also need to create a part that resembles Thomas' face (the one you see here is NOT a LEGO piece). He would also need some stickers for his number "1" and perhaps for his round windows, and he would look smart indeed:-)
I grew up reading the definitive Rev. W. Awdry tales. Wonderful set of tales. Why isn't there a shot of them fishing in his tank for the fish that go in by mistake? Riddle part 3: What is decidedly not spikey?
