Oh, and something I forgot to add and cannot believe I didn't notice this until about a week ago.
How many Land Before Time antagonists do we have that conspire against each other to the point of
murder? I mean sure, in the earlier sequels, the songs tend to empathize the flaws of our antagonists and how they bully eachother, (i.e. "Eggs", "When You're Big" to a smaller extent, "Who Needs You?", "Standing Tough") and bad guys do inevitably back stab one another in other media when something doesn't completely go their way or if one party cannot uphold their end of the bargain. But in the Land Before Time series? Just look at this dialogue right here:
Sierra: "That's it, I had it with that blowhard!"
Rinkus: "I know, I know, but be patient, let him lead us to the stone."
Sierra: "Oh yeah, I get ya, then it'll be time to make a few changes in the pecking order..."
Right in between the song, just those few lines, while Pterano is fanning himself about how awesome he is and how other dinosaurs could just see how great he is/bring them all to paradise, the hench flyers get fed up and conspire within that moment. That's pretty heavy stuff in a sequel of that type in the time it was released.
So yeah, just adding more reason why I chose "Very Important Creature" as my favorite villain's song.
