You've ran over a midget campoanologist and he (she ?) is stuck in the top lefthand corner of the fan shroud.
Or it could be Tiddles, Mrs Curtain Twitchers cat, from number 32.
Perhaps all that's left of him is his collar ?
Anywat he, she, It, probably moved towards the engine under accelleration, got swiped by the fan and was flung out and onto the road.
No more ding-a-ling.
Check your sump for dents.
