Sonic Boom, Season 1

Sticks:
They really look alike. We need to figure out how to tell them apart.

Amy:
I know. Our Knuckles can wear something to distinguish himself, but which one's our Knuckles?

Knuckles:
Well, that depends. What does distinguish mean? [Amy runs off and returns with a blue party hat.] No way! I'm not wearing that!

Mirror Knuckles:
I'd be honored to wear your ridiculous hat my dear. [puts the hat on]

Amy:
Ahh...

Sonic:
He may look like Knuckles, but he sure doesn't talk like him.

Knuckles:
Hey! I talked gooder than you.

Tails:
[thinking] There's a perfectly rational explanation for this. [Everyone looks and listens to Tails, but after a long wait, he shrugs.] I just haven't figured it out yet. [Everyone groans at Tails.]

Mirror Knuckles:
Worry not, young Tails. Be diligent. In time, the answer will seek you.

Knuckles:
Whoa. I sound like a fortune cookie! [tries to eat his right arm] Yeah, but I don't taste like one.

Mirror Knuckles:
There's only one person smart enough to unravel this enigma.
