Start shopping for jungle-themed pajamas. On June 4th, the Cal Academy of Sciences opens its doors for an after-hours sleepover for adults-only (this is the only sleepover night that you don't  have to be with a kid to get in) — a chance to get all Night at the Museum with the Academy's creatures—both taxidermied and alive.

What goes down? Well, most importantly, you'll get to find out what the Academy's celebrities — Pierre the wet-suit clad penguin, Lemondrop the python (who's been all over Pandora lately) and Claude the albino alligator —get into after the lights go out. But also, there will be free planetarium-gazing, drinks at The Academy Cafe, entrance to the Rainforests of the World exhibit, a complimentary continental breakfast and the chance to lay out in the African Hall and count sheep with the cheetahs. 

Tickets are $119 for  non-members, $99 for members, but we're giving away a pair of tickets to a lucky newsletter subscriber.Not signed up for our daily newsletters? Remedy that here.
