Deltarune Chapter 5 has finally been released, and it wouldn't be a proper chapter without some puzzles to test you. After enjoying the festival for a while with Noelle, you're going to end up back in the Dark World chasing after a new antagonist. The first section of the Dark World after the festival is rather light on combat, and instead, you'll be solving puzzles and trying to find your way through the Garden in search of Asgore and Flowery.

The first block puzzle is simple enough, as you just have to push the block onto the pressure plate. However, the second block puzzle, which is also called the mushroom puzzle, is a bit more frustrating, and I actually hate how many times I had to redo it before I got it right.

The creature guarding the path that's blocked by spikes tells you that he can give you the solution to the puzzle if you give him a mushroom when you interact with him. This is easy enough. If you head to the south, there's a little area with a bunch of mushrooms. Pick your favorite and interact with it. This brings up a prompt asking if you want to take a bite, and you confirm that you do, which puts a little mushroom on top of your head.

Take the mushroom back to the creature. He accepts it, but then says you need to give him two mushrooms if you want to solve the puzzle.

This is where the puzzle gets frustrating. When you go back to interact with the mushrooms, you can now grab two, four, or six mushrooms. It doesn't matter which you pick, since you need at least two. Of course, they stack on top of your head into a mushroom tower, which means all except one mushroom will be knocked off your head when you go under the stick.

However, this is the important part. When the mushrooms fall off, a bunch of nearby objects turn into foxes and swarm the mushrooms before returning to where they were. One of those foxes happens to turn into the block that you need to get from one patch to the second patch with the pressure plate.

You can repeat this part as many times as you need to in order to figure out which fox is the block. Then, grab that fox when it comes to eat a mushroom. Now, you can carry over to the patch where you couldn't slide the block, letting you set it down. Once on the ground, it turns back into a block. From here, it's simple enough to push the block onto the pressure plate, removing the spikes and clearing your path.

While this section of the chapter feels rather calm, you want to stay on the lookout for hidden items and secrets, especially since you can grab some restoration items here that you might end up needing later once you face the chapter's bosses. In the meantime, it's time to continue on the main path and try to figure out what Flowery wants and why Kris' dad is involved in this new mess in the Dark World of Deltarune.
