I remember these kids films from the 80s
One was about a mystical happy land that has a shadow cast upon it and a nearby castle that holds a dragon aka the shadow. The main characters take a boat to the castle to defeat this "shadow". Second film is with a girl as the main character who finds a portal to a weird place. In the place there is a tree with fruit that you can't pick that is covered by a glass dome. She has to pick one fruit to give to another character to survive. An evil lady lives in the place. Another film is about fairies that come to take the main character away to their fairyland at night when he/she dreams. The boy or girl have to help them save their fairyland. Last film is with two kids that enter another realm via boat,and when they enter the city they are captured and sentenced to death by being swallowed by a monster. Kind of like the monster in return of the jedi that people accidentally would slide into and get swallowed. They end up getting saved by someone. Maybe their parents. I can't fully remember
