Like Rocket Scientist, Miner Threat is easy to deal with if you have plants that attack zombies behind them, like Starfruit and Bonk Choy. Sweet Potato is very good at taking care of him, since Miner Threat will pop out of the ground when she’s nearby. Additionally, Sweet Potato's Hot damage type lets her take less damage from Miner Threat due to his Earthy type.
His appearance is different from his counterpart in Plants vs. Zombies, since he now wears a yellow hat instead of a white one. Besides that he also has brown hair instead of black and his pickaxe is slightly larger than the one Digger Zombie has.
Earlier, when he was defeated, his body would disappear, leaving only his head on the ground.
