If you have been following my channel on YouTube, you know that I started posting Minecraft Pocket Edition videos this past few weeks. There's a lot you can do in MCPE and even more so with the help of add-ons.
One of the best resource pack add ons out there today is the Minecraft Story Mode S2. It features many different mobs like giant Enderman, Magma Golem, Giant Golem that shoots fireball and many more.
The most interesting mob included in this resource pack is the giant golem. It's very huge and powerful and it shoots fireballs. Here's a video me demonstrating the Story Mode S2 resource pack and showing how to spawn the Giant Golem in Minecraft PE Pocket Edition.
