"But what if you cannot find any boulders, Mr. Littlefoot?"
"If you can't find any, then then that just means you are not looking hard enough."
Yeah, child! Do you expect instant gratification? The comic had me snickering 'till the end after that!
"If you're ever afraid, alone, sad, happy, or anything in between really, singing a song is really the most optimal thing you can do."
Flyer: "What if you don't like to sing?"
Littlefoot's reaction, HA HA HA!!!!

I think he's trying to explain the phenomena of plot armour and crowd singing, without really realising that they're phenomena in the first place.
Littlefoot: "... I'm sorry ... what was that?"
Flyer: "What if you don't like singing?"
Littlefoot: "... I hear the words, but I don't understand the way you're putting them together. I know! Why don't you sing it?"
Flyer: "I don't want to."
Littlefoot: "... Come again?"
Flyer: "I don't want to sing. I don't like singing."
Littlefoot: (Thinking)
He's trying to speak to me, I just know it.
