|First appearance||"The Late Philip J. Fry" (6ACV07)|
The Dumblocks are a humanoid species of stupid, vicious brutes who live underground. They are one of the two species the human evolution will be diverged into by the year 5000000. The Dumblocks will live side-by-side with the intellectually and morally advanced creatures until 5000005, when they will rebel and take over Earth.
- The Dumblocks resemble the Morlocks from the 1960 film adaptation of H. G. Wells' early science fiction novella The Time Machine, and are presumably named for them.
- They are also similar to Peaches from Bender's Game.
Female intellectually and morally advanced creature: Since your time, human evolution has diverged.
Male intellectually and morally advanced creature: There are we, advanced in intellect and morality.
Female intellectually and morally advanced creature: And the Dumblocks, stupid, vicious brutes, who live underground.
