|Voiced by||Frank Welker|
The Tunneling Horror is a giant leech who appears in Bender's Game. Zoidberg is originally mistaken for the Tunneling Horror by Leela. He is later exonerated when the Tunneling Horror emerges and tries to eat Bender. Frydo later beats it away it with a throw from the Die of Power.
It bears a resemblance to a tape worm from Teenage Mutant Leela's Hurdles.
