I know the popular analogy is to compare the story of Water Horse to ET (just as people compare Wall-E to ET). But in the look of the glossy head of the Lochness Monster in the WWII Scotland movie reminds me of the glossy heads of the plastic toys from 1988. Maybe it's just me.
I wanted to see what the head was made of and just did a quick little google search, that proved pretty fruitless. Except for the fact that I saw that one of the waterhorse model heads is for sale on ebay. (Pictured left). This head must belong to adult version of the Water Horse (note the larger Mohawk) and is guessed to be made out of fiberglass...but what is the cute plasticy head made of of? Latex? Silicon? No clue, but currently the ebay auctioned head is less than a dollar.
