" 
They no let Pterano be in TV show!"
"I cannot believe that young Sharptooth we hatched eat Littlefoot! He was so young!" Petrie, Land Before Time II: Great Valley Adventure, upon finding a missing Chomper and Littlefoot.
Another one, pretty hilarious one: "Mama actually punish me for breaking the rules! She never do that before! No fair! Me often go wandering during middle of night and come back in early morning and get little sleep and me never get punished before!"
"Me cannot believe that me stupid enough to sniff stinky plants on Mysterious Island. Their smell really make me eyes water!"
"No narrator, Littlefoot and Ali supposed to get married and have big family, not have her leave. Bring her back! Bring her back! NOOOOOOOOOOOOO!" Petrie at the end of the fourth movie
"Loofah and Doofah are driving me nuts! Me cannot take them anymore! Arrrgggh! Ahhhhh!" - Petrie losing it in Wisdom of Friends (which I liked by the way, but heard that many didn't)
"First Chomper bite Cera, then he bite me wing! This really hurt!" -Petrie in movie II.
"Me laugh me head off at stupid egg stealers! They could have gone around bend but they jump instead and fell and get really hurt. They dumber than bunch of rocks! Me laugh so hard that me cry!" - Petrie, movie II
"We bring in Sharptooth egg and Cera got bitten in tail! Then we get chased by evil egg stealers and barely escape liquid fire! How could this day get any worse?" (Chomper's parents come into view.) "Life no fair!" (Starts bawling) - Petrie, movie II
"Why don't me have a girlfriend? Littlefoot have Ali! Why me get no one?" - Petrie
"Me can't believe they banish Pterano for five long cold times! That too harsh!" -Petrie, movie VII
"Me cannot believe they make me fly across Big Water! Me really scared!" - Petrie, movie V
And, here's a classic one:
Ducky: Poor, poor Petrie. Poor poor Petrie!
Petrie: (Flying next to her) Yeah, me no believe that me get killed by Sharptooth either! (Bawls)
-Petrie, first movie
"No, mean Sharptooth! Don't eat Petrie! You can eat Cera, but no eat Petrie! Please!" - Petrie, crying as the Sharptooth, who turns out to be Chomper, corners them.
"Me just realized, they forgot to put me dad in movies! Me so unhappy!"
"Me waited long time to see Ali come back yet she only talk for about a few minutes! That's not fair!" - Petrie, TV Series
Bizarre one:
"Ech! Me wish Ruby would stop kissing me! Me not her boyfriend!" - Petrie, TV Series
"Cera poked me in tush with her horn! That really hurt!"
"Spike have club tail breath again! Ugggghhh!"
"Wow, we finally get Chomper to eat plants. He eat hard sweets. We did it! We did it! Me so happy that me cry!" - Petrie, near end of "Through the Eyes of a Spiketail"
