I've always wanted to be able to set up animal traps. Minecraft feels like a game where you're struggling to survive, and building animal traps seems like an important part of survival. So I've created a block that can attract animals. If the animal is able to touch the BaitBox, it will consume the bait and won't be hungry for awhile. If you place a jack-o-lantern in the BaitBox, animals will run away from it. The block can also be turned off with a redstone input.

These items attract these animals:
wheat - cows / sheep
seeds - chicken
bone - wolf
cooked pork - pig
silk - spider
rotten flesh - zombie
cake - creeper
arrow - skeleton
cobblestone - enderman
iron - pigzombie
gold - villager
pumpkin - makes everyone run away
