How do you explain this?

Remove the three lowest matches heading North West to South East
Use 1 to make a rhombus at the top
Use the second to extend the one you have just placed further to the NorthWest
lace the third one parallel to that one forming the tail

Not doing it if there is no prize

Make the top bit a square using the bottom match; the other two match moves then become obvious.
