×You have more than one caber available. What can the extra ones do for you?

×Cabers block explosions.

×Creating a small notch might be useful.

Decoy caber was inside the gel.

That way I could create a 1 tile explosion. I thought it was cool but brought me no further to the solution.
After that decoys are blown up so I can make 2 3-tile explosions and 1 1-tile explosion.

Maybe I should bring some assumptions out of the way first.
- To even start the room I need 1 keg at the top which creates an entry point. Is this any good?
- I need to bomb the gel (solve the puzzle) and finally can clear the whole gel down to the baby with the sword.
- I don't have any interaction with decoys have cabers and Beethro has a sword.

×The thing about that arrangement is that the decoys get blown up so you can only use it once.

You should be able to tweak it into one that lets them survive.

×Should our decoys be facing the same direction, or different ones? If they're different, would those directions be symmetrical (e.g. facing both NW and SW, or NE or SE, or some other such pair?)

When we blow up a keg, should both of them survive for every one? Or does one of them have to get blown up at one point?

×The decoys should be facing so that they both survive the explosions.
