a phone call with Panther Primitives

Me: Yeah, I'd like to return my tent.
Them: What was the matter with it?
ME: The Zombies tore right through it.
Them: Zombies?
Me: Yeah. They came right up onto my lawn during a garden party. We tried to fight them off, and the pavilion was useless. I mean, a few got tangled up in the ropes, but all in all, it didn't impede the assault in the slightest.
Them: Ah. We recommend the Henry VIII Pavilion for battling the undead. The shape confuses them.
Me: Hm...what would be the cost to upgrade?
