full size Snooki Plays Games With a Penguin Balloon in Seaside on June 17, 2012

Snooki is already notorious for her peeing issues, and now that she’s pregnant all bets are off on controlling her bladder.

In an exclusive sneak peek for tonight’s episode of Snooki & JWOWW from Entertainment Weekly, Snooki gets scared pee-less when she and JWOWW visit a ninja-themed locale that apparently features ninjas jumping out of dark corners and scaring everyone. When one ninja surprises Snooki and Jenni in an elevator, the pregnant reality star starts to laugh.

“I just peed! I just peed!”

Snooki explains that she had been “holding in her pee for 20 minutes” and that the shock of seeing the ninja caused her to lose all control.

Poor Snooks! Well, she’s had more embarrassing moments captured on camera, right?

Watch the exclusive sneak peek on EW.com and watch the episode tonight at 10 p.m. ET on MTV.
