In this video, I cover getting all the Teensies and Cups for the "Dungeon Chase" level of "Rescue Elysia" contained within "Teensies in Trouble".
0:16 - Again, kind of bizarre that there's even a free-roam portion at all. Why not just start right with Murfy? Seems like a weird programming quirk on their part.
1:04 - The timing for this part sucks, as the window of opportunity is very small. Not much advice that I can give you.
I didn't show off Elysia, but she's basically a palette swap of Barbara. I play as her later on, and I show the character description for her there.
