Magical Jungle Bag

The Magical Jungle Bag is a tool that is sold by the Druid in Hardmode. It allows the player to convert Mud Blocks into Jungle Grass, as though they were using Jungle Grass Seeds. This can be done indefinitely, as it costs mana rather than using the item, thus may prove useful in creating an artificial Jungle biome without additional costs.

Trivia

 * Magic seed bags for Corruption, Crimson and Hallow likely do not exist as the source of the bags are the Druid NPC, who may be against the spread of evil.
