I also saw this candy shop in Bruges:
It made me think of one of the taglines for Cookie Crisp cereal (or, more accurately, cookies in the name of cereal!): "Coooookie Crisp!" howled by Chip the Dog. Here's a video if you have no idea what I'm talking about and didn't spent Saturday mornings in the early 90s having this drilled in your head.
I'm not sure how the "Flemish" version would be pronounced.
