Alright, my thoughts of this one...
The first scene has some really funny things in it. Littlefoot accidently falling into the water, Ducky+Petrie doing the same on purpose(actually only Ducky) and Petrie's line after that

It was kinda cute how Ducky said that they'd complement each other..
Oh, and Spike gets stuck
next scene: The next funny thing is that LF, Ducky and Petrie try to get Spike unstuck

Oh common! Spike's burping how ridiculous... but funny

another time Spike gets himself into danger

He falls into a cave under the earth. And it's not the Tinysaurusses' cave
Of course Spike has to eat something there

and of course Ducky has to stay there...
next scene: Spike eats but then whispering appeared from everywhere, oh no... and then three big shadows appears... and then... RATS?!?!? O_O
next scene: Oh, Cera, Chomper and Ruby are playing tag I guess. Chomper chomps into some grass, hehe. Then Littlefoot appears, he and Petrie tell them the story... Cera's sarcasm

Oh, and Ruby quotes, I like them.
So Mr. Thicknose show up out of nowhere. Some discussion about the different kinds I see. Well, he helps them, great!
Cera: "I believe it when I see it"
Chomper: "Speaking of it... you're it!"

Had to smile for at least one minute

next scene: those little... rats are talking... oh my...
So Spike's the Big Wise eh?
Beyond the Mysterious Beyond eh Above: no comment ...
And Spike eats as if nothing happens
next scene: nice little Mr. Threehorn moment

next scene: Spike's burping again and those little rats still believe he's the Wise One

at least this little trick of Spike is kinda funny... and they bring him shiny stones... !
next scene: Mr. Thicknose vs. Mr. Threehorn yay!!!
next scene: hehe they tickle Spike to wake him up

good advice for Ducky in case Spike rolls on her at night.
What's the Great Hideous Beast?!?
Ohh, THAT LITTLE CUTE THING????? Ridiculous! Well, at least Spike safed those rats from it in a funny way...
next scene: another arguement I see... Petrie already falls from the tree guys!
My Way: Ehh... forget what I just said... better argue than sing!
So another time the kids have to find solutions as Kor stated. Ducky brings the idea up and Ruby worked it out.
next scene: It seems as if Spike becomes homesick...
Yes, pull gang, pull!
Spike says Goodbye to those rats... eh no comment, where the hell's the GHB??!?!??
Oh, the Gang pulls her up... Ducky talks to her..cuuuuuuuuuute!
BUUUUURRRP!!! Spike appears behind them

Another epic Ruby line.
And of course Thicknose and Topsy are still arguing. When they find out Spike has already been safed Topsy's like

and Thicknose like
"You're the one who started arguing!" Awesome Mister Thicknose

and even after that they can't stop
All in all the episode was okay. There are some aspects I really like( the first scene in general, Thicknose and Topsy arguing and the GHB as well as the general funnyness and a whole bunch of Ruby lines, besides the fact that the kids do something while the grown-ups are arguing) while I strongly dislike others(mainly the fact they used those little annoying rats :huh: )
The whole plot that happens under the earth in that little cave( except the scenes with the GHB) are very weak imo... I just don't like them as well as the fact they haven't used dinosaurs but annoying little mammals:x
About the thing that the grown-ups always argue and so on... : I like it under the circumstances of tLBT though it actually is the wrong message what Kor stated above.
