Hoi! I lived in the Netherlands for a little bit, but I never picked up much of the Dutch language besides "lekker" and "gezellig." Thought I'd try out your game though! Let's see...

1. Boter bij de vis: maybe this is something that's very tempting...that would lure in someone the way you would normally lure a fish except instead of a worm, you can use butter?

2. Het gaat van een leien dakje: I'm guessing something that goes from a slate roof is something that won't stick? It tries to stick, but eventually slides off. Like something you're trying to learn perhaps, i.e. a new skill?

3. Bepakt en bezakt: This one seems pretty straightforward. If something is packed and sacked, it's ready to go! Right?

Okay, well, I tried :) Doei!
