As far as aim, Riku considered it, but this served as a decent warning shot. It was also fortunate for Roxas because with those comments, Riku's sympathy would have been lacking and he might've insisted that the "show must go on." Sora's initial comment earned him a glare, and a twist of his own "tail" as a threat that he could get whipped too.

Riku grumbled when Sora suggested the song. "Can and WILL are two different things," he muttered. Originally they'd planned for them all to sing this at some point in their impromptu skit, but apparently that'd been changed, and there wasn't much he could do about it. Grouchily he picked up the guitar again and began to play. His voice was mediocre, but at least his guitar skills were good.

"Many years ago
when the earth was much younger,
there were no human beings around.
When the dinosaurs walked the ground
shook with thunder.
It was a terrible sound.

What happened to the dinosaurs?
How did they grow?
Were they stronger, quite bold, or sharp as I've been told?
I guess you soon will know, know, know, know!
I guess you soon will know!

Many were quite large,
very quick or much stronger.
They needed more than being just buff.
When the dinosaurs knew their stuff
they lived longer.
Smartness just wasn’t so rough

What happened to the dinosaurs?
How did they grow?
Were they stronger, quite bold, or sharp as I've been told?
I guess you soon will know, know, know, know!
I guess you soon will know!

Since dinos had brains
It was a revolution.
They’d grown superior and advanced.
When the dinosaurs wore the pants
in evolution, (Riku shot a look at the other two)
Humans hadn’t a chance

That happened to the dinosaurs!
Now can I go?
They were stronger, quite bold, and sharp I've been told!
I guess that you now know, know, know, know!
Man, this is really low."
