The portal page is a loading nightmare for me at the moment, but I did notice a new game up under the Beta list. I only got a few plays in so far as everything is acting quirky.
Quick Screenshot and description below in the spoiler.
Just by what I played the whole concept is similar to garage sale in that you are catching the dropping petpets while avoiding bad items and catching good items. The difference is the water gun that lets you shoot floating power ups or enemies, which makes it a little more interesting then just the back and forth catching.
