Mabel's - hands off! Aztec hula dancer with one eye, dice, toothbrush - in fridge.
Effervescent! Apple fritter! Riboflavin!
This is what Mabel had Rumble McSkirmish read from the paper. The last line is disgusting, so I didn't put it here.
You need an amiable sidekick with a pickup truck? / Where does Soos get all this stuff?
Soos is not an idiot, as proven by his use of the word amiable (meaning lovable), and there is a slight continuity error here. If Soos is rich enough to afford a pickup truck and the S.S. Cool Dude, he shouldn't be still living with his grandmother. Sure, some would say Soos' paycheck is their only source of income, but Stan says he works for free.
Hey, do you smell anger and hormones? ... muffin
Robbie's explosion muffin appears on the fence behind Rumble at the foot of the watertower.
That guy's got, like, a black belt wrapped around his black belt.
Rumble and Dipper's fight / peace sign in background
I just found the irony interesting.
The bigger they are, the harder they depixellate.
This quote, said by Isabella in Phineas and Ferb, sums up perfectly how Dipper defeated Rumble.
Thank you for playing. DIP
After playing some video games, the game asks you to type in three letters so you can record your high score. Dipper typed in DIP, which could easily be short for his name. But most people type in their initials. Dipper's last name is Pines, so it's entirely possible that DIP is his initials. We will probably find out, considering that Alex Hirsch has said that Dipper and Mabel's middle names are their father and mother's first names, respectively. He probably wouldn't say that if we weren't going to find out what those names are.
Sorry, Dipper, but your Wendy is in another castle.
Referencing Super Mario Bros. When you beat a mini-boss, Toad tells you "Thank you Mario! But our princess is in another castle."
