Jellyfish, crab and broken bottles, oh my!

Jellyfish of some kind. They didn't have any tentacles that we could see and were relatively safe to touch although unnerving to do so. For a brief moment - about 30 minutes or so - we couldn't go wading because they were so thick in the water, and it was freaky to feel them brushing up against you.
Some kind of crab?
One of the gals tried to pop the cap using a bottle opener that was built into the kitchen counter and broke the rim of her beer. Another gal said, "You must've done it wrong." She tried to open hers the same way and this was the result.

I admit I'm having a bit of a writer's block. I keep trying to think of something to write about that might be more interesting to other readers and blanking.
