the rip

i have had this idea for quite a while of someone getting stuck in rip of the ocean while trying to surf but the ocean is not made up of water and it acts more like a massive bean bag still not quite sure on how it could end though whether some one comes and rescues him from this giant bean bag or if he would just stay still and start to sink he could swim out of the rip still very unsure how that one will work. but i will keep working at it.
