What is the machine that Mr Caulkiss is constructing in his laboratory?

Who are the 'Little Ones' that Craylene Caulkiss is feeding in the cellar?

What is the purpose of the Box of Tools?

Why does Mr Scrab live under a grating in the back yard?

Why does Melestrina Quode keep talking about 'the Great Return'?

What makes a pair of underpants go scurrying across the floor?

And who is the Vicar of Morbing Vyle?
