Kourtney Kardashian Penelope Scotland Disick Mason Dash Disick Aquarium of the Pacific

Kourtney Kardashian took son Mason and daughter Penelope to the Aquarium of the Pacific in Long Beach on Saturday, and it looks like everyone had a blast! And not only that, but in between juggling her two young kids and trying to keep it low key in the crowd, Kourt was able to Instagram a pretty pic of some jellyfish.

But where was baby daddy Scott Disick? The other day he was tweeting about cars and plugging a lingerie line (and this was NOT something from the Kardashians collection), and as far as we know he wasn't hosting any ragers in Vegas over the weekend. What gives?
