The overall plot of the movie as far as I remember was that some kids managed to find their way to some type of prison setting ran by monsters.the kids plot their escape. They get out and the kids parents are somehow non the wiser.i distinctively remember the kids being made to eat a disgusting food and a girl who had been in the setting for longer than the main character told him to pinch his nose so that it didn’t taste as bad.the movie was in color.i saw this film sometime in the early 2000’s but it could have been any amount of years older than then.Please help!
