Got bored and tried this for fun. Original link is broken since Quizilla died in 2014 so I'm just gonna use the alternatives to find my inner dino.

1) https://www.buzzfeed.com/mathewguiver/which-the-land-before-time-character-are-you?utm_term=.wi2AAvjJKz#.sg2BBK20e9

...that's really accurate, actually.

(this one is worded in a very in-character way, eg. there are a ton of options with 'fly' in it, so it sounds rather easy to cheese your way to being a Petrie, for example; or aggressive answers are usually peak Cera)

Your Result: Cera

Cera is a friend of Littlefoot in The Land Before Time film series. She is a Triceratops. Cera is a bossy and snobby but sometimes nice baby dinosaur who tries her best to show no fear. She has no problem bragging about her accomplishments, even going so far as to fabricate entire portions to make herself seem more brave, but will run away at the first sign of any real danger. She is also very sweet and caring, but that side of her personality is usually masked by her normally gruff exterior. Cera also has a fear of heights, as seen when she and her friends have to cross a ravine. She is also afraid of lightning.

Breakdown:
64% Cera
44% Ducky
44% Petrie
44% Spike
20% Littlefoot

...I'm frankly shocked for this one. The only thing I share with Cera irl is my gruff sarcasm!

Panicky about big world? Gentle and brave? (excuse me, brave? what?) Sounds roughly correct.

4) https://www.proprofs.com/quiz-school/story.php?title=1dq-which-land-before-time-character-are-you

You got: Spike   

You are Spike! Laid back and relaxed, you take your time and assess every situation. You are very protective of your friends

Laid back and relaxed is right!


...and just for fun I found two more.

(this one's unusual because you get a slider per question to actually rank how much of an impact your answers have on judging who you are)

Little Foot -- You are a natural born leader and a good friend (100%)         
Spike -- You are there but not really noticed (85%)         
Ducky -- You are a happy, friendly person (73%)         
Petrie -- You are a comedian always quick to laugh (49%)         
Sharp Tooth -- The enemy and the hatred based of the whole movie (22%)         
Cera -- You can be bossy but do come through in the end (0%)

Really? Littlefoot top? I agree with the order of the rest, but really?

(this one's hilarious because each question corresponds to every single sequel up to XIII)

Which Land Before Time character are you? Cera

You're quite quick-tempered and stubborn. Like Littlefoot there is a mystery behind your parents, in LBT your supposed mother is shown to look exactly like Mr. Threehorn, she is never shown again, then in LBT11 Tria came into the story.

Think my snark came through for me this one...

Also, at the end of it all, I didn't get a single Ducky.
I am sad, I am, I am...

For some reason, the results page didn't display for me on the 5th quiz. But for the others, in order I got 2 Cera, 2 Littlefoot, and... Ruby. Interesting.

Not so much an outsider, but I do consider myself to be quite intelligent.

Haha, I love Cera's expression there.

I took the same quiz and this time around I got Petrie.

Ducky is not pleased on your behalf, nope nope nope!

 

With everybody taking these, I feel like this forum could use an official Land Before Time quiz. I think we could come up with better questions/answers than the people who made the other quizzes, anybody else agree?

Eh...who knows? That could be a fun thing to arrange. And since your our expert on the rainbowfaces, perhaps you could have answers that pertain to them?
