Knickknack Alley is a location based in Monte d'Or, seen in Professor Layton and the Miracle Mask. Few shops can be found here, including Guy's toy store and a fruit store. The road along Knickknack Alley connects the Gallery Plaza and Oasis Street. In the UK version, the name is stylized as "Knick-Knack Alley".
Knickknack is a small alleyway, with large buildings containing a fruit shop and Guy's toy shop. Fruit are displayed outside the fruit store, and likewise toys are scattered out the front of the toy store. A smaller alley passage leads to a dead-end next to Guy's toy shop, and a flight of stairs leads up to Oasis Street.
