Flying spider spawner [1.1.0/1.0.0]

As previously noted, utilizing this seed in Minecraft PE, you will encounter a floating spider spawner on the surface. You will spawn on an island; follow the arrow and you will soon discover this phenomenon.

Continue your journey until you discover a mesa biome.

Approach the biome, then head to the opposite side of the small peninsula; there you will discover a spawner.

It is advisable to visit during the day, as approaching closely at night can be quite challenging.

It’s an incredibly unusual seed; in all my time playing the game, I’ve never encountered anything like this before.
