Goblins!

Listen, listen. 
( Hand behind ear) 

Goblins are there. 
(Point to the door) 

Hear them tiptoe To your chair? 

Don't speak a word. 
(Finger to lips) 

Don't go "ah-choo!" 
( finger under nose) 

Don't move about. 
( sit very still with arms close to sides)

Or they'll get YOU!!!
 (Shout "you" and Jump up with arms extended)
(Say it in a quiet, spooky voice and finish with a shout.
