FINALLY done with these. Turns out getting food items to look rotten is VERY difficult and time consuming when you only have 256 pixels to work with...

Closed again, since Pufferfish isn't even supposed to be spoilable. The philosophy behind things like Poisonous Potatoes, Spider Eyes, and Pufferfish not being able to spoil is that is gives them an actual benefit as a food source. In Vanilla, things like Poisionous Potatoes are completely useless, since there are MUCH more useful food items that DON'T give you Poison effects. However, by making these foods not spoilable, it gives them a benefit that makes them actually worthwhile as a backup food supply, since their Poison effects aren't as bad as that of spoiled foods.
