Here is an idea. I have been using the Arthur Stead cd "Skullopini", with the Skeleton in the Closet effect. Kids love the music.
Here is how I use it in a Gospel setting.
After the trick, I talk about how sometimes we get a little mixed up with sin, just like my friend Mr. Bones got mixed up. I then talk about some of the things we get mixed up in: lying,stealing, cheating, etc. But if we confess our sins to God, the Bible says He is Faithful to forgive us our sins, and help us to overcome.
I use this to lead into teaching about repentance.
