I love them too.
The ones I had was cream cheese with fresh dill minced in it. Here are some variations. The one with the ranch dressing powder mixed in would be good, maybe with some fresh dill sprinkled on top of the cucumber.

There are a lot of fancy ways that add in other ingrediants, or shred the cucumber into the mix, but I feel like the simpler, the better.
