Fandom's Enemies table lists 17 Drill to Earth's Core enemies, from the 100 HP Goblin to the 10,000 HP Goblin Champion. 11 of them have their own page here with how they attack and how to beat them. Enemy health and damage grow with depth, so the numbers below are base values for where each enemy first shows up.
Most enemy corpses can be sold for coins or thrown into the drill's furnace as fuel; the special enemies (the Watcher, Bombo, Blinker, Fuel Leech, Ore Worm and Wolf Bat) can be neither. A Golden corpse sells for three times the coins, and most other mutations add half again.
