Supposed to be quite yummy though our Prophet(Peace be upon Him) himself never ate it. No it is not haraam, but He Muhammad didn't chose to cos it was not a food known to him.
Back in SL we get creatures like so all over grassy areas, and a few used to pop up in our school playground every now and then.Some kids would flee petrified so "brave" kids like myself would enjoy a good laugh..cruel I know!
