Strange Morphing Object Captured,

I was sky-watching from the back garden when I spotted a very bizarre object moving across the sky. The object was seemingly morphing into different shapes and was moving at a high rate of speed. I managed to take four photographs capturing the strange morphing ability of this object. In photograph four, the object looks like it has taken on the form of a creature with a gun, which is very odd. What on earth could this object be? How was this thing able to change shape, so quickly while moving across the sky? I had never seen anything quite like this before. The photographs were taken on the 16th of January 2016, at Newton Abbot Devon England.
