WARNING: if you encounter one or more of these strange vinyl visitors, remain calm. Talk in an unhurried, offhanded even casual manner and don't make sudden jerky movements like you usually do. Then slowly and suspiciously work your way around to its backside and quickly flip open the small valve (genitalia?) found on the center of the disturbing and disproportionately shaped head. Its very life force will exhale and then you can roll it up and stash it under your mattress or anyplace else you may be standing near to that is easy to stuff things like that under unless you want to keep it and play with it later. Be very afraid. Or not. Whatever.
