To The Limit: Hamster Ghost Vampire

You could try some of the more interesting lot traits to make his life more intense. I've never been brave enough to use the cursed trait maybe you could try that one. Creepy Crawlies is another fun trait that works in San Myshuno though the sims don't get poisoned by their invasive jungle fauna. To get that you might have to set him on a little jungle adventure, let him try all the trap options without having to figure them out.
