Attacc

Attacc was an iron golem that, along with Protecc, helped keep the villager vending machine safe.

He was killed by skeletons in the 11th episode of the series ("We Lost Three Friends In Minecraft Hardcore..!"). Notably, he's the only golem that dropped a flower.

In his memory a disk a creeper had dropped from a skeleton killing it was played afterwards than a new Iron Golem named Smacc was made to keep his old friend Protecc some company. (him and Smacc never met)
