Mary Poppins doesn't only fly with umbrellas, you know. She's in an elite group of characters who qualify for Floating Is Fun multiple times under different tags. What did Angela Lansbury put in these balloons?
I apologize for the gap between posts here. I didn't forget about my airheads here! I encountered some other unexpected floating objects and they've been living rent-free in my head ever since. I asked about them and I'll post one when I get the chance.
