I used to watch a show when I was little, probably the 80's since I can hardly remember it. It is likely Canadian but I don't know for sure.

There was a brother and a sister that found an amulet (I think in their attic) and it transported them to a magical world. There were puppets there. The main bad guy was a wizard and he was a puppet. I think I remember that most of his spells failed. I believe he also had a cheeky raven as a pet. I asked my dad about it, and he said he remembers that they were looking for their dad.

Does anyone know what this show was called?

Never mind I figured it out! It was Blizzard Island! TVArchive.ca - Blizzard Island (http://www.tvarchive.ca/database/19449/blizzard_island/details/)
