SpongeBob, before we're torn to shreds, I'd like to thank you for helping me look for Spot.

Aw, it was nothing. Hey, speaking of Spots. Did yo always have a double pupil?

Plankton:
A double what? [pulls Spot off eye] Spot! [dramatic music plays in the background] Thank entropy you're safe! You were hiding on my optical cornea the whole time! You sneaky little amoeba, you.

[Spot barks and licks Plankton. Plankton laughs]

SpongeBob:
Aw, I'm glad you found Spot. [animals shrieking] Unfortunately, the animals found us too.

Plankton:
Good-bye, Spot. I guess this is the end of the road for us.

Spot, no!

Wow, Spot! You saved us!

I taught him everything he knows!
