Transcript:
Marigold: A unicorn walks among these people... and they know so little of it. Sometimes, I would like to turn off the magical shield of boringness, and be seen in all my glory.
Phoebe: So why don't you?
Marigold: Unicorn rules.
Phoebe: Unioncorn!
The shield doesn’t make Marigold invisible. It just stops people from registering that a unicorn is a big deal.
