The Thomas the Train snack train I made for my son's third birthday. It was so easy and cheap to make. It's just 3, two packs of aluminum loaf pans from Walmart at 2.50 each (mine came with plastic lids-great for leftovers), a roll of black electrical tape (.60 cents) and of course, Thomas. We had our Thomas, didn't have to buy one.
