Aldus is a mild-mannered man whose excessively friendly attitude seems to draw only suspicion. He frequently anticipates Layton's next destination and pops up to give him advice, only to quickly run off again. He's crazy about wooden boxes and takes one with him everywhere he goes...supposedly.
An unsettlingly friendly and mild-mannered gentleman who frequently anticipates Layton's next destination, popping up to give him advice, only to run off again. He is rumoured to take his favourite wooden box with him wherever he goes.
Later on, Aldus appeared on Great Ely Street and told Layton and his companions to tap a near by pipe ten times. In doing so gave them a strange old fossil. Aldus told them to start a collection with it, adding the Collection minigame to the professor's trunk.
Close to the beginning of the game, Aldus appears in Celebration Boulevard to explain to the Professor about hint coins. He tells you to find a wooden box, and you can't find it without zooming in, and he explains how. Layton opens the box and finds a hint coin.
Aldus's next significant appearance was in Knick Knack Alley, where you had to zoom in to find him. There, he tells you to look in the metal box near the small building, and there the Professor finds a Stylish Clay Pot. Aldus then gives Layton the Collecion Box, for an extra add-on to the investigation.
He appears again when the player has completed the story, telling them how to go back to Stansbury or Monte d'Or, and how to alternate between day and night via the Dromedary hotel room and Hershel's room at Riverside Cottage.
