CRUSH
Whoa. Kill the motor, dude. Let us see what Squirt does flying solo.
SQUIRT
Whoa! Whoa! That was so cool! Hey dad, did you see that? Did you see me? Did you see
what I did?
CRUSH
You so totally rock, Squirt! So give me some fin..noggin..
CRUSH/SQUIRT
..dude!
CRUSH
Oh, intro. Jellyman, Offspring. Offspring, Jellyman.
SQUIRT
Jellies? Sweet.
CRUSH
Totally.
MARLIN
Well, apparently, I must've done something you all like. Heh, uh, dudes.
SQUIRT
You rock, dude.
MARLIN
Ow.
CRUSH
Curl away, my son. Aw, it's awesome, Jellyman. Little dudes are just eggs, leave 'em
on the beach to hatch, then coo-coo-ca-choo, they find their way back to the big 'ol blue.
MARLIN
No idea.
The turtle father is encouraging the young one to explore alone. Perhaps "curl" refers to something that he is doing? Was it moving in some sort of curve? Did it refer to the EAC being a twisting spiral at that point?
Just guessing. Haven't watched it for a while.
The turtles talk in a sort of hippy - style English: It is intended to be a little cryptic & distinctly chilled-out.
