Catherine is a shopkeeper that sells all available items in Blinx the Time Sweeper.
She appears in 9 different shops, 1 in each of the first 8 stages, each with its own exclusive stage items and regular items, and the ninth accessible in Momentopolis after surviving the boss rush before the final battle.
- In the first game, if you were to buy a new jacket then go back to the very first shop, if you examine your old blue jacket now available at the Shop she says "This is the best one for you, Blinx."
- If all shop emblems are turned in at once at the Time Factory, an image of Catherine titled "Bromide" will be added to your gallery.
