Okay so i think it was a kids kivie from like the 90s or early 2000s cos I remember i watched it multiple times when i was like 7-8 and im 17 now. But i literally dont remember it except that they sat on the floor and it was black. The main character was a young girl who i think was going to be kidnapped by witches(?) they had magic anyways and at the end the sidekick of the witch(?) got turned into a dog. The movie /dvd poster was purple and i think the main character the little girl was holding a crystal ball in it. I know this isnt any information at all but it’s driving me crazy
Just a guess, maybe?:
“Bibi Blocksberg” (2002)
Kids movie, girl, witch, crystal ball, human becomes an animal.
You can watch the full movie here (it is in its original German):
