I really hated that I couldn't send my sim out for a fishing trip without coming home with less-than-fresh fish so I created a fishing cooler. This portable cooler allows you to store fish in it so they will keep fresh longer and it comes with some drinks that have a chance to give your sim a boost while they're fishing.
When Sims take the Final Exam there is a random Loot where they cheat and either fail or succeed at cheating. Every Sim that is not at least lvl 4 in Mischief has a high Chance to fail and get caught. I changed the random loot a bit: Only Sims with at least level 6 in Mischief should cheat and only have a chance to fail when they have the Clumsy Trait.
