Bubble Creek

There's this wee stream that runs down the side of the house and it bubbles. Not that every so often a little bubble of air escapes from the bottom but rather when there has been a heavy rain fall it properly fizzes.

I've seen enough horror films and invasion style tv series to know that when a stream/pond/ocean bubbles there is DEFINITELY something under that rocking surface. Clever aliens, sharks, creepy divers that know to pop up right through that whirlpool. So there's the mystery of Ovenstone, what lies beneath? Come on now, in such a small hamlet (and with the help of a pebble) you have to create some excitement!
