A redstone bug was a hostile mob present in Java Edition 2.0.


Redstone bugs can spawn if a redstone wire increases the strength. The chance that they spawn is 1%. The chance increases for every redstone bug in a 7x7x7 area by 5%. The Color value of the bug can reach from 33292288 to 66846720.


Redstone bugs, effectively being reskinned silverfish, shared all of their behavior.
