Fall In PoseBarrel (with bonus fun) by goodstuff.

What happens when you lean to far into a barrel? You fall in of course! This is a sculpted barrel with original "Fall In" pose. Your legs kick back and forth in a futile effort to climb back out! Great oddball item to have around the house! Another great product from goodstuff!

Neat Hack: Go into edit/build mode and, in the first tab, change left click option from "sit" to "touch". Then, in the second tab, change barrel to "physical". Now, anytime somebody "falls in" you can use your mouse/cursor to grab the barrel and roll it, toss it, or hold it in the air and drop it with them still inside kicking (and probably screaming)!
