Minecraft Skeletons appear in the game, "Minecraft." They make their Adventure Time debut in the episode, "Diamonds and Lemons," among some other hostile mobs. They also appeared to help Marceline and Princess Bubblegum to build a Windmill.
They appear to be skeletons with blocky bodies. Normally, they carry bows and arrows, but the ones that build Marceline's Windmill had yellow and red construction caps.
- This is the only mob in the game with any actual lines
- Marceline has been shown to have the ability to summon these Minecraft Skeletons.
