There was one like that in my room in Nairobi. It was the size of a saucer, I swear! It was super fast and flat and I was told it was good to have because it would catch other things that could bite/sting me. **shudders** So every night I would talk to it, sort of make a deal like, "I will not scream every time I see you if you make an effort to keep that from happening."

I only saw it twice. It was FAST. WHOA
