I just came across this show on my TV a few hours ago, called "Goldie and Bear" it's on Disney Junior.
One of the episodes I just saw is called "Pinocchio-itis" one of the main characters, Goldie! Her nose grows each time she lies about something, and suffers from the strange illness the whole episode.
I couldn't find any other websites that had the full episode except Amazon and Netflix, but did come across this short clip on Youtube that is from the same episode, just to give you idea of what happens to her in the episode. ^_^
