11,000 Meters Underwater is the thirteenth episode in season 4 of the series 2013.


When the cybeavers are packing to go in a mission in their submarine, Fabian doesn't resist the curiosity and sneaks into the submarine as a stowaway, leaving P.T., Cris and Josh behind who refused to go due to the danger. The cybeavers are planning to go where no land and probably mutated creature has ever come, the bottom of the Mariana Trench. As they get closer, things start getting weird. At that depth, animals haven't mutated, but they still look really bizarre. Will the cybeavers get it? Will Fabian be found?

  • This episode introduces the abyssal fish, the first 2013 species that hasn't mutate.
