Bella drops her frog, pulls a handful of something powdery and green out of her sleeve, and throws it at the bat things. She hits four of the flock, and those retreat into miscellaneous exits, shrieking, but the others get at her and start nibbling at bits of Bella that aren't covered by armor. Bella does her best to swat them away - none of them is bigger than size of her outstretched hand - but there's about forty. She eventually gives up on doing anything about their insistence on nibbling on her and attempts to help Sherlock out of the water, upon which exit the bat things begin to nibble Sherlock too.
