As Ruby was flying all the way to Virpos City, she then wanted to take a view beyond the sky.

"Wow, this is real!" Ruby wondered

However, Ruby forgot she was in very high air. This can cause her to have breathing problems yet again. Luckily, she was able to find an Oxygen Mask to help her breathe in high altitudes. She then puts it on and continues to fly.
