There's another movie or cartoon/movie I've thought of for many years but can't remember much about to figure out the title. It's very vague and I'm not sure if I remember it correctly. I think it was about a little girl or a little girl and boy, possibly siblings. It also involves little creatures. I sort of remember them as either cartoons or animated creatures. I think the girl is friends with them or finds the door to their world and goes to visit. She might change into a cartoon or character herself when in their world. I have no clue if any of this makes any sense to anyone. I really hope it does because I remember being fond of it. Thanks for any help. This would have been in the early to mid 80's.

are you thinking of 'the hugga bunch'?

the little girl is friends with the hugga bunch, they're puppets. And they go through her closet mirror to where they live.

hope I helped =]

I looked it up and I believe that is the movie. It's so weird how you rememeber things differently that you saw when you were a kid. Thanks for your answer. I've been thinking/wondering about the name of that for years. Now it's one less thing to waste brain cells on. Thanks again!

Is it "Dot and the Kangaroo?"

No, it was the Hugga Bunch, but thanks.
