Streets Doctor Who advertisement (TV story)

A  was produced in 1981 to advertise the Streets Doctor Who Ice Cream. The advertisement was first released in late November 1981 in Australia. The promotional campaign had an extremely short run, due to Peter Davison already having premiered as the Fifth Doctor by the time the advertisement aired. (VV 5)

The segment is of great note for being the first known licensed Doctor Who animation ever created.

Synopsis
The Doctor and K9 hunt for the very first Dr. Who ice cream treat.

Plot
The Doctor and K9 enter the TARDIS, and travel to an ice cavern, where they find the first Doctor Who Ice Cream encased in a prism. Suddenly, a doppelganger of the Doctor arrives, who is soon revealed to be the shape-shifting alien Necros. Necros intends to steal the Ice Cream, but is defeated by a massive laser beam. The Doctor says it's a "pity he couldn't stay", and takes some of the ice cream for himself. K9 asks the Doctor who invented them, causing the Doctor to respond affirmingly with, "Who else, K9?"
