×We can get into a position where a gel baby stands on each plate while we're invisible fairly easily by simply inserting the gel babies into the top-right force arrows in reverse order (and putting the Wubba in the middle so as to stagger and hit the topmost plate), but of course, the Briar doesn't grow in that scenario.

If we step on the plate to open the Briar, the gel babies--obviously--move out of the way, and move away from the topmost plate. It would maybe be doable like this if there was a third invisiblity potion to pause them again on the respective plates, but there's not one.

The only thing we can think of is that we probably aren't using the Golems as intended, but how to use THOSE is its own conundrum. One probably has to go at (13,25) to stop the babies from entering the water (a Wubba could be used in theory, but you'd have to insert a living golem in to stagger them or just outright re-order the babies when shoving them into the top right arrows), but the other one seems less than useless somehow, despite us knowing we're probably missing SOMETHING and this guy probably has to sit near a plate somewhere.

The result is either getting the briar gates to stay open, but the briar can't grow, or vice versa; the briar can grow, but the right briar's gate is closed and it's a moot point.

×What do you think the hot tiles are for?

×Earnest question; are we meant to use them to torch a wubba at some point? Or do they only exist to destroy a rock golem or two? Also, a wubba could block the water, but we're yet to find a reason to do that over golem rubble.

We can't think of any use for the hot tiles that helps in stalling the gel babies (or a wubba or the rock golems) while being able to grow the briar, short of maybe having a Wubba temporarily act as a buffer before it gets burnt, if this is what you're going after, but we might just be saying that because this room isn't exactly clear on what you need to do. Or we're just kinda blind. Could honestly believe either/or at the moment.

×So you've already thought of blocking off the water to hold a gel baby in place.

How could you block off another tile on the diagonal to prevent a baby from getting past it?

×Wait, are they actually numbered? That would've been a nice detail to catch on to. Still, how we solved it felt a lot cooler by processing just what we were meant to do, so we're not complaining.

×I just mean the number that they move within a turn, which can be found by right clicking the monster. Agreed that the intended solution is much more satisfying.
