The obsidian golem mod, adds an obsidian golem which can be spawned into Minecraft Pocket Edition. To spawn the golem, place two obsidian blocks, and then one either side with a pumpkin head on top (similar to how you spawn an iron golem). Then click the pumpkin with an iron hoe and the golem will spawn. You can then fight with the golem, or let him protect you! Currently the goelm makes a cow sound.
