Orange traffic cone
From A KoL Wiki

orange traffic cone
This is a big cone of bright orange plastic. You have no recollection of how or where you got it, but it's like I always say -- it's not a good night unless you end up with a traffic cone!

Notes
- This item appeared in players' inventories the next morning if they had seen the To the Rescue stupor adventure, available by adventuring in a St. Sneaky Pete's Day Stupor on St Sneaky Pete's Day I. The adventure would only occur if they were wielding a cheap plastic bottle opener.
- It was originally just called a "traffic cone", the orange in the name came later. The equivalent on the second holiday was a yellow traffic cone, and on the third holiday it was a red traffic cone. Jick says these will likely not be available on future St Sneaky Pete's Days.
