The Giant was chasing very fast, and Ybur, disliking how slow Saraphido was running, simply swallowed her whole and started bouncing and rolling like a massive ball through the forest, knocking the trees all askew. Saraphido was being tossed around inside it, her eyes spinning in circles.
Ybur's heart was about to burst with excitement. Since entering this Dream Realm Domain, its core emotions felt as if they were being pulled, intensifying incredibly. The heart represents emotions, so in this mysterious place, all sorts of emotions were amplified. Ybur was well aware of this but couldn't control himself… and didn't really want to. It's just playing! After all, it was only an avatar that had come in, which couldn't die anyway! Without the fear of death, all that was left was excitement.
