Halloween // Need 30 minute storytime idea for 7 year olds

I am hosting a 30 minute (maximum) zoom storytime for 2nd graders next week. Since it's Halloween week, of course I want to do spooky stories. I was thinking something like "Bunnicula" would be ideal but it's not the right length. Does anyone have any suggestions for spooky stories at that level that will come in under 30 minutes for either one or two stories?
