Kryten uses the time wand to resurrect Birdman's pet sparrow Pete but accidentally de-evolves him into a T. Rex that rampages through the ship. Lister and Rimmer are brought before Captain Hollister who orders them to change Pete back.
Kryten has accidentally turned Birdman's pet bird "Pete" into a T-Rex which has gone on a rampage on-board Red Dwarf. With the crew frozen in time, Rimmer, Lister, Kryten, Kochanski, The Cat and Holly attempt to stop Pete, and get back the Time Wand which Pete has eaten, and restore Pete back to normal before the freeze wears off.—Daniel Williamson
