As Higsby goes on a trip to Netopia collecting rare chips and installing Chip Traders in other countries; his shop is closed during early events. During the latter half of the game he returns to ACDC Town and reopens his shop.
Higsby goes on vacation to YumLand and his shop is closed again, but he returns later and helps Lan during their chase for BubbleMan. The shop has a Chip Trader and a Number Trader. There is a large poster of Zero (White version) or SharkMan (Blue version) near Higsby.
The Sign Comp is an anti-theft device that sets off a very noisy alarm if someone tries to steal a chip. It has the shape of a NumberMan display.
Higsby's shop is the first Chip Shop available. Players have the option to buy a single Battle Chip, 10 Battle Chips or Get info on gameplay.
In the events that follow if Lan faces Higsby in the Den City Tournament, a guy is planning to close down his shop and replace it with a shop that sells brushes, though Lan manages to help out by gathering posters for his assistant.
