I remember watching a movie when I was growing up about a girl who is given strawberries by a man and she ends up falling asleep because the man wants to kidnap her. She is sitting by a river when it happens. I believe it was Japanese type animation (similar to the Last Unicorn movie). I don't really remember anything else besides that. Sorry I know it's vague.

Katy samples some intoxicating
Berries in

Fantastic Adventures of Unico (81)

Katy has a brief encounter with a handsome young
Nobleman at the edge of the forest. Katy sneaks
Into the forest in hopes of finding him. She finds
And eats some intoxicating berries in the woods
And falls under his spell. She feels drawn toward
His dark castle.
