Family Ness (1984-85)
Family Ness was about a family of Loch Ness Monsters who befriended the MacTout family, imparticularly Elspeth and Angus who were brother and sister. The children could call upon the 'Nessies' in the loch simply by blowing on their "thistle whistles".
What I remember the most about Family Ness is that it had THE best theme tune called "You'll never find a Nessie in the Zoo!"
The Poddington Peas (1989)
The Poddington Peas were a community of peas who lived at the bottom of the garden. The characters all had pea related names like Sweet-pea, Hap-pea, Creep-pea and would you believe it Black Eyed-pea (no joke!) I wonder if that's where they got the name from! Only one series of The Poddington Peas was ever made! Boooooo!
