Emerald thinks an invisibility potion would be nice to hide himself, but that fireball one sounds good as well. Emerald asks about them.

"Fireball one is pretty neat. Just be careful if you decide on that one. Just because you'd be immune to the fireball doesn't mean you'd be immune to the force of the blast, or the molten shards of glass from the bottle."

"As for the Invisibility potion, it's nice too. I remember using it heavily when I was in my voyeur phase. Anyway, just remember that it only makes you invisible. You can still be heard, touched, and smelled."

Emerald asks if maybe they could do both.

"Don't get greedy now, lil' perv!" Joyride says wagging a disapproving hoof with a smile, "Just one. Pick wisely!"
