The Dreamstone (1990)

Season 1 generally

Continuity mistake: Frizz and Nug switch colours in a couple of episodes of the show, and Nug has Frizz's glass colour too.

Urpgor: Why must I always deliver my creations into the hands of halfwits who can hardly remember their own names?

The Robo Bird - S2-E4

Trivia: Urpgor falling down a cliffside twice is a reference to the Wile E. Coyote and Road Runner shorts.
