G'nichi's New Home

The lid does not budge. This is because there is a magical kettle bell that cannot be lifted save by TRUE HEROES sitting on top of it, and frightened children are usually not true heroes.
There is also music blasting through it, which is to say the kids can actually faintly hear it through the huge iron lid. After enough screaming it does go "silent" (from their side).
After a few moments there's thumping from the top of the lid.
"I ain't fallin' for that again, clown!"
