An entry in Fortnightly Topic Challenge #35: Restricted Title 1. Title based on this xkcd.
This is a continuation of Barrel - Part 1, but this puzzle is still self-contained.
Continued in Barrel - Part 3, Barrel - Part 4, and Barrel - Part 5.
Oh no Carol, there'll be barrel peril! This time, it's a $6\times 6$ warehouse, and you need to get a "special" red barrel out of the warehouse through the only exit. (it's "special" because it's actually dynamite, hence the peril. You don't want your warehouse to blow up.) You must do this without letting any other barrels out of the warehouse. To review, a barrel takes up one cell when upright, and two cells when laid down. Maneuvering the barrels works as follows:
- An upright barrel can be tipped over to lie flat.
- A laid down barrel can either roll to its sides or be propped up.
Specifically, consider the following image.
The solid barrels in this example can move to any of their adjacent outlines, assuming those spaces are unoccupied by other barrels. A barrel cannot move past the wall, either.
Here is a diagram of the warehouse, with the exit shown by the missing wall in the top right. Please show how to get the red barrel (dynamite) out of the warehouse. You are not explicitly required to do this in the minimum number of moves, but it's quicker to present the answer if there are fewer moves, no? Please feel free to combine several moves into a single image with arrows and/or text explanation in order to shorten the answer.
