The vine beast reached the edge of the desert as it followed its lunch.
Jay made it to the middle of the desert right as the beast entered. He had to do something to slow the beast down, but the damn lizards were almost right underneath him, each having a fruit in their mouths ready to stick to Jay's flesh.
He had to either keep moving or die.
A few of the underground lizards haphazardly poked their heads up right below a mushroom fruit, and became victims themselves, releasing little cooing noises as they were slowly pulled into the air, becoming food for the mushrooms, which disappeared shortly after.
When a mushroom disappeared it made some extra space and even allowed the beast to run faster.
The mushrooms at the centre of the desert were larger, taller, and one was right in the middle of Jay's path, so the skeletons mostly trimmed every single one underneath.
