Are you talking about this object from the Island Living EP? It's called the 'Happy Place Pavilion' in the catalog.

You can do a search by pack if you know which one it came from and find it that way. I have to do that a lot. The build/buy catalog isn't sorted in the most logical way in my opinion. I agree object names can make it tough to find things too. While it's okay to give them fun names and I love the funny descriptions sometimes, it's frustrating when you can't find things as a result.
