The creature was making some sort of mini-earthquakes around it at each step, and was drooling all over the place, excited to find one of its favorite mushrooms...
This wasn't enough to wake up the tiny thing. Once Plume sleeps, nearly nothing is able to wake it up...

That was unfortunate. Because the huge beast just found its favorite mushroom. And swallowed it whole. With the ground around it... And also the tiny halfling sleeping under it.
When it woke up, Plume didn't really understand what happened, but kinda felt like something changed... The place was all slimy and the smell was horrible. And it was suddely moving a lot...

The tiny halfling is too confused to really understand what's going on...
