Heheheh, I loved Petrie's "It Booms.." line. I also liked when Petrie talked about how the Smokey Mountains were shakey.
Petrie: "It all shakey...like Cera when she mad."
Cera: "Huh?"
Cera's reaction was priceless. XD I also liked when Ducky said.
"Just because the mountain is as shakey as Cera, that does not mean it is scary as Cera. Oh, no, no, no." (Cera gives her a dirty look) "Um, you know what I mean."
I started laughing at those parts as well as everything else mentioned. XD
