Robbie surfaced to the cheers and whoops of his friends. He waved and basked in their admiration. Only Erika wore and expression of concern, watching the water ripple and thrash, the surface growing more agitated. Her eyes widened when the translucent muzzle of a huge, watery artillery gun began to form out at the deep end.
None of them were prepared for the return fire.
