Solutions are classified as ammo for the Clentaminator, all of which are sold by the Steampunker with the exception of Dark Blue Solution, which is sold by Truffle. They can refer to any of the following:
- There is no Solution which could spread the Jungle by itself, however using a Green Solution on a Mushroom Grass turns it into a Jungle Grass instead.
- Jungle can only be converted into a Mushroom biome.
- If Corruption/Crimson spreads to the jungle and the player uses a Clentaminator with Green Solution, it will be converted into Purity instead of a Jungle.
