The gang decide to follow Rimmer's lead and run away from Pete, now de-evolved into a Tyrannosaurus rex, but he manages to eat the time wand. Meanwhile, Kryten's penis Archie (which he has made himself in an effort to be reclassified as a man) escapes and he is prevented from chasing it when the Canaries are detailed to stop Pete after his deadly rampage through the supply decks.
Trivia- Originally the script included a sequence of Kryten trying to fight with the T-Rex, before getting abruptly shooed off by its foot.
