With the Spider Bonanza modification, you will populate Minecraft PE with a large variety of spiders. In total, there are more than twenty types of them in Minecraft PE. Some of them are much larger than vanilla ones, and have unique textures and effects.
In addition, spiders of the Spider Bonanza addon will drop various items in Minecraft Pocket Edition that cannot be crafted, such as a fireball. The mod works in MCPE on version 1.16. And so that there are no glitches in Minecraft Pocket Edition, activate the experimental mode.
