The April 2025 edition of Minecraft Marketplace Pass and Realms Plus has arrived with an impressive lineup of 25 new content pieces centered around a science theme. From the expansive Naturalist Add-On 3.0 with over 100 animal species to the experimental Mob Fusion world that lets you combine creatures, this month's offerings provide exciting new ways to experience the blocky universe.
Naturalist Add-On 3.0: A Wildlife Revolution
The standout addition this month is Starfish Studios' Naturalist Add-On, now updated to version 3.0. This comprehensive wildlife expansion introduces over 100 types of animals to your Minecraft world, each appearing in their appropriate biomes.
The collection includes familiar favorites like zebras, elephants, and lions alongside more unusual creatures such as caterpillars, Komodo dragons, and even microscopic-inspired ants. Underwater explorers will encounter sharks and whales, while arctic adventurers might stumble upon mammoths in snowy landscapes.

What makes this add-on particularly impressive is the attention to detail. Animals behave according to their natural tendencies, creating more immersive ecosystems throughout your world. Whether you're watching ostriches at dusk or tigers prowling through jungles, the Naturalist Add-On transforms the wildlife experience in Minecraft.
Create Bizarre Creatures with Mob Fusion
Science takes an experimental turn with Lifeboat's Mob Fusion world. This creative addition allows players to combine two different mobs in a specially designed fusion machine, resulting in bizarre hybrid creatures with mixed abilities and appearances.

Want to see what happens when you combine a zombie with a cow head? Or perhaps a pig and a creeper? The fusion machine makes these strange combinations possible, creating unique gameplay opportunities and visual oddities that will delight experimental players.
What Can You Create in the Fusion Machine?
The possibilities seem nearly endless with the fusion machine. Players can experiment with combining hostile and passive mobs, resulting in creatures with unpredictable behaviors. The world features various biomes and environments designed specifically to showcase your strange creations in their new habitats.
Horror Fans Rejoice: The Backrooms Experience
For those who enjoy a scare, April's update delivers two complementary Backrooms-themed items. Float Studios' "The Backrooms Pink Dreams" world offers a horror experience with an unsettling pink aesthetic and entities that defy natural laws. Jump scares and eerie environments await the brave who venture into this disturbing realm.

To enhance the experience, GoE-Craft's The Backrooms Texture Pack transforms standard blocks and items to create an even more immersive horror atmosphere. The combination of these two items creates one of the most unsettling experiences available in the Marketplace.
