It aired around 4 hours ago in Canada on YTV. Here's some basic info:
Airdate (Canada): June 29th, 2007
Description: On the day of the Falling Rocks of Many Nights (meteor shower), Ruby remembers a memory of her family meeting at Hanging Rock when she lived in the Mysterious Beyond. Ruby adventures alone to find her family, but her friends come along to help. They meet Skip along the way, a mammal who knows the Mysterious Beyond very well, and the gang learns an important lesson of being family.
Songs: Up in the Sky (shares melody with The Lone Dinosaur), and Feel So Happy (was interrupted in the middle)
I found it weird when they interrupted the song when Redclaw and his fast biters came in. It was quite unexpected, and I hope they don't do that again... though I can imagine some people in this forum are already sick of the Feel So Happy song. ;P
This episode was also the first time we ever see Ruby's family not in a flashback.
