I'm wondering a bit here... A pleasure planet, specifically if being so for Slimes, who procreate through division so it's not likely to be a red light planet. They probably have different ways of loosening up and relaxing than, say, a massage and a hot spring. They probably don't have the same dancing and partying scene either, with their odd structure. They are definitely not eating the same way as most other sapient organisms. And getting away from the family and getting a bit of alone time, well, we've seen how casually they spawn off offspring and how little parental guidance is in that - unless that's a Eugene thing specifically. Now gambling and the like, it feels like Eugene is bent towards not losing money, but perhaps slimes have similar culture to other sapients there.
So, what are the Slimey ways of pleasure and recreation? What aspects of relaxing, cutting loose and having a good time, escaping the drudgery of mundane life, of socialising etc. do slimes prefer?
