Littlefoot is horrified

[rhombus]

Littlefoot:  "What are my grandparents doing?!"

Petrie:  "Me could have lived without seeing that." 

[Dalekdino]

He's been shown video footage from the first film were he first met Petrie and is a bit embarssed by it.
Littlefoot: Did I really yell like a maniac like that!?  

[raniwasacyborg]

"We've been contracted for how many more sequels!?"

[The Anonymous Person]

Littlefoot: What...are Cera and Ducky doing to each other?

Petrie: That...just not right...

[Dosu2Dinner]

Littlefoot:........Is that what I think it is???
Petrie: Yeah, sorry, but...I really needed to go...
Spike: Could be worse...

[rhombus]

Littlefoot:  What is Chomper doing?

Petrie:  "He about to be bopped!"

[Ducky123]

Littlefoot: "Holy Yellowbelly! What on earth are Ali and Rhett doing!?"
Petrie: "They kissing..."
Littlefoot:  
Petrie: "Well, you no luck today. There be enough pretty Ali's out there..."
Littlefoot:  
Spike: "Gee Petrie, very sensitive of you..."

[rhombus]

Parents:  "Okay, children... Since you have survived Red Claw's attacks several dozen times now, we think that you would be the best choice to end his reign of terror once and for all.  Come back when you are all done."

Littlefoot:  

Parents:  "Good luck!"

Petrie (looks at Littlefoot):  "Me tell you this would happen!  We go on too many adventures and our parents too lazy!"

*Spike grumbles*

[Sneak]

Littlefoot: No.... IT CAN'T BE POSSIBLE! (c)
*SHARPTOOTH'S ROAR*

[Flathead770]

Petrie: Me think integration by parts is needed for this problem.

[Littlefoot505]

Petrie: Me think integration by parts is needed for this problem.

Nice one! How about this one?

Petrie: On your final, you take derivative of function using limit definition. That cool?

[Gentle Sharptooth]

Littlefoot: You don’t want me to be the leader?!

Petrie: Me told you. The Lone Dinosaur bit was too much.

Littlefoot is balancing a redox equation, and Petrie just told him that it has to be in a basic solution.
