"More Tribbles, More Troubles" is the fifth episode of the first season of the animated American science fiction television series Star Trek.
It first aired in the NBC Saturday morning lineup on October 6, 1973, and was written by David Gerrold as a sequel to his Original Series episode "The Trouble with Tribbles".
[note 1] It features actor Stanley Adams reprising his role of trader Cyrano Jones, and the return of the fuzzy, rapidly reproducing creatures called tribbles.
In this episode, Kirk must figure out why the Klingons are trying to get a hold of Cyrano Jones while simultaneously protecting two automated grain carriers.
The Klingons attack again, disabling the engines of the remaining cargo ship and bathing the Enterprise in a radiation which rapidly increases the growth of the tribbles aboard.
"[6] The Star Trek: The Original Series season 2 remastered DVD set also included special features for 'Tribbles', including original series episode "The Trouble with Tribbles" and the episodes "Trials and Tribblations" from Star Trek: Deep Space Nine and "More Tribbles, More Trouble" from TAS.
