The Swamp
![]() |
Purple Heart Trees Swamps now have their own native type of tree called the Purple Heart. These trees are generally larger than a standard oak but smaller than a fancy oak. Purple Heart trees grow vines on their leaves and trunk. Purple Hearts feature a full Purple Colored Wood Set. (See in Block Sets) |
|---|---|
![]() |
Sinking Mud Watch your step when in swamps—the mud near water may just be a new variant called Sinking Mud. Most entities that walk onto it will quickly find themselves sinking into its muddy embrace. If you’re traversing the boggiest parts, bring Leather Boots or be prepared to meet the consequences. |
![]() |
Firefly Bushes Firefly Bushes have been backported to 1.21.1 and expanded upon. These bushes can be found all over the swamps and at night they light up with bright fireflies. Use a bottle on one to catch and release them anywhere! |
![]() |
Belladonna The Belladonna is a new unique small flower, native to the swamp. It’s poisonous—any entity that touches it becomes poisoned. Belladonnas can be crafted into purple dye. |
![]() |
Swamp Reeds Swamp Reeds are a new type of aquatic foliage found in shallow swamp waters. They generate in dense groups and can be crafted into 2 Brown Dye. |
Block Sets

Expanded Mud Set The Mud block set has been greatly expanded with:

Dung Set A new Dung block set has been introduced with:

Mobs
![]() |
Impillagers Impillagers are a new trader class of mob. They live in a unique village, only found in swamp biomes. (See Structures) They have their own independent professions and are neutral, but they fight hostile mobs & attack Villagers. |
|---|---|
![]() |
Dung Golem Dung Golems are crafted from a Dung Block and a Carved Pumpkin. Impillagers spawn these golems to help in combat. They shoot dung from their arm cannon and are permanently Smelly. |
Impillager Professions
![]() |
Dung Collector These Impillagers aren’t the cleanest, but they’re crafty—collecting village dung and turning it into blocks! They use the Waste Basket as their job block, which automatically collects dung from nearby farm animals. |
|---|---|
![]() |
Banker Bankers trade gold with outsiders to improve the village’s flow of gold— though some of their Gold Coins look a bit… off lately. They use the Vault as their job block, a lockable container accessible only by crouch-right-click. |
![]() |
Musician Musicians spend their days jamming out and hunting new tunes. They use the Jukebox as their job block, always ready to swap songs for coins. |
Structures
![]() |
Swamp Ruins Swamps now have their own unique ruins for you to discover! Make sure to bring your Brush. Each Swamp Ruin has one Frog Mask; don’t miss it—it will guide you to the elusive and rare Frog Temple. |
|---|---|
![]() |
Frog Temple Not much is known about the history of the mighty Frog Temple—the current residents certainly weren't its builders. It’s now the heart of the Impillager Village. Rumor has it the Impillagers didn’t loot it thoroughly, so you might uncover some interesting artifacts. |
![]() |
Single Village House Impillagers feel vulnerable on the ground, even in swamp safety. As a result, they built their houses in the trees surrounding the Frog Temple. We don’t know what drives this behavior—perhaps something from their past before arriving in the swamps? |
![]() |
Double Tree House The Impillagers connect their tree houses when they’re close enough. After all, why descend to the ground when you can cross by bridge? |
![]() |
Dung Collector’s House The Dung Collector made this little spot home—it might look like a bush, but they deemed it perfect for their collection. It might smell a bit, though. |
![]() |
Musician’s House This used to be a statue, but the Musician turned it into a community dance floor. You’ll often find them by the jukebox, picking the next best track! |
![]() |
Explosive Expert’s House Watch your step here—this small ruin was taken over by the self-proclaimed Explosives Expert to store their gear. It won’t explode. Probably. |
