Olson is a minor character in Professor Layton and the Diabolical Box.
Olson wore a pale orange jacket over a cream-colored polo shirt with dark green pants. He wore glasses to assist his terrible eyesight.
- Olson is the only person in Folsense whom the player doesn't need to give a cup of tea to.
Olson doesn't draw much attention from people, and he isn't much for cracking a joke. His eyesight is so bad that, even with glasses on, the illusion of Folsense could melt away and Olson wouldn't notice any difference.
