Giant Flytraps

Giant flytraps could be a one block tall, 2 block wide rare plant/flower that grows in the swamp biome. Similar to how a berry bush inflicts damage on contact, a giant flytrap could cause poison damage on contact to mimic the acid of real life flytraps. Using bonemeal on a giant flytrap could cause it to sprout a unique harvestable flower that, when planted next to a block of water, could grow into a giant flytrap.
