Having already partly decided on making the ancient stone watchtower, her temporary home while she underwent her fifth evolution, Scaly began approaching the stone structure with an eager skip in her steps. Excitement about her coming evolution causing her to increase her speed ever so slightly to reach the watchtower just a bit faster.
The only reason she didn't directly rush forward was the presence of the monsters in the tall grass all around the hill that the ancient stone tower was situated on top of.
Although these monsters wouldn't be impossible for her to deal with given her current strength, she didn't really want to waste any time fighting them and just wanted to get to find somewhere inside the ancient stone watchtower where she could go through her fifth evolution.
