Lamoic Bibber is the town in "Mr Gum". Every character lives there and the locations are:

Main street: A street where many shops are; Peter lives in an apartment there but she just never said it and Alan Taylor gets the books from the library of history and the museum of snow and ice.  

Boasters' Hill: The hill of boasters and the home of St. Mucin's School for the Poor (Alan's home).

The Neighbourhood: Mr Gum and Polly live in this place; it's also home to Old Granny, Benny McLenny and Jonathan Ripples.
