None of them will go and have a look as they are all too scared. The Tweenies all decide what they would each like it to be but they do not convince themselves. To their horror Judy pulls a book from behind the curtains but she does not seem to have seen anything scary so during their story about Mr. Underbed they all keep an eye on the surprise area curtains. When the story is finished they admit to Judy that they are scared of what might be there. Judy seems to know what it is and encourages them to go and have a look.
