There was something suspicious about this. See the hole? Somehow this deterred dogs from thinking there was anyone in this tunnel.

And here is another trap. There might not be spikes down below but why would you want to fall into the enemy's territory?

Just be careful.

More spikes. You understand these are in several places, right?

Now what is this?

Not so innocent anymore. This is a different trap than the previous picture but it is the same idea. These are bamboo spikes.

It's a cute little door. Innocent enough, right?
