Suspicious Blocks
by OctopusPith
Suspicious Blocks changes familiar Minecraft blocks and armor stands so that ordinary objects can behave in unexpected ways, for NeoForge on 1.21.1.
What it does
Familiar blocks such as composters, end rods, blaze rods, stripped wood, pointed dripstone and lightning rods gain hidden behaviors while keeping a mostly original look. A suspicious composter adds an interaction the standard composter lacks, and some blocks get a bottom section that can be used. The additions are meant to blend with the original blocks rather than stand out from them, and more suspicious blocks are planned for later updates.
Armor stands are the main mechanic. Over time they begin to think for themselves and can wander around, and coating them in honeycomb wax stops the process. Nearby black cats suppress the sentient behavior. A configuration file changes many of these armor stand mechanics, and administrator commands let operators inspect armor stand states and trigger behaviors for testing. The mod is published for NeoForge only, for 1.21.1, and it runs on client and server, so the server and every player need it. It is released under All rights reserved and is not open source.
Key features
Suspicious composters
Composters gain a suspicious interaction that differs from the standard composter's behavior.
Coated end rods
End rods can be coated with several materials, each giving a special behavior and a visual variation.

Armor stands become sentient over time and then roam around the world instead of staying in place.
Configurable armor stand mechanics

Use cases
Testing armor stand behavior
Administrator commands report armor stand status and sentience and can trigger a roam or a panic reaction, which helps when checking the mod's behavior.
Adding unusual hazards to a world
Server owners who want familiar objects to behave unexpectedly can tune the configuration file to set how armor stands develop and act.
Who it’s for: Players who want familiar blocks and armor stands to behave in unexpected ways, and server owners who want to tune or test those mechanics. Both the server and every player need the mod installed.

What the author says
Suspicious Blocks expands familiar Minecraft blocks and entities with unusual hidden behaviors while keeping a mostly vanilla-style appearance. The mod is designed around the idea that ordinary objects may contain unexpected mechanics. More suspicious blocks and features may be added in future updates.
