Ok. So, when I was little I used to rent a vhs from Schnucks grocery story movie rentals. It was probably an 80's or 90's movie. It was about a girl who looked out her window and then had koala friends(? I think they were koalas. Something fluffy and care bear like). They went to a secret land and to get there they had to go through a tunnel. I seem to recall her going through the tunnel with a bicycle? Anyway, the animation was very pastel colored. I think she had to save the secret world or something.
I know this is really non-specific, but it's a big part of my childhood and if anyone has any idea... please let me know.

One of the Noozles movies maybe?
