In Shark Tale
Luca first appeared when Don Lino and the puffer fish Mr.Sykes were having a talk inside the sharks' Headquarters. Lino told Sykes to work for his sons afterwards. Sykes said it's possible with Frankie, but Lenny, he's not so sure. Speechless, Lino sighed,Luca. and asked Luca to play the music record, only the music didn't go to what Lino expected it to go.
Mr. Sykes: Lenny?! You've got to be kidding, Lino. That kid ain't a killer.
Lino: I'm dead serious.
[The talk between Lino and Sykes pause, as they heard the music record slip a little]
[Luca sets the record tape right, but accidentally sets it to Baby Got Back by Sir Mix A Lot. Lino and Sykes stares at him, and Luca quickly turns the record off.]
Luca: Hay, Boss, Big Butts!
[Lino and Sykes exchange an eye-roll, and both ignored him.]
Luca is shown to be quite clumsy when Lino told him to do anything, like when Lino told him to play a recording of something. Still, it is shown that Luca shares Lino's worry about Lenny after Frankie died.
Giuseppe: Signore, Lenny's missing, ever since after the funeral yesterday.
Luca: Hope he's safe.
He frequently annoys Lino; yet, he's still loyal to him. Luca is stupid at times, asking Oscar to nod his head over the phone, mistaking Lino to work at the pizza shop and pouring coffee underwater. Luca plays the piano and his favorite song is "Baby Got Back" by Sir Mix-A-Lot.
Lino(not knowing that Oscar has taken Sykes's place on the phone): Shut up? Shut up? You don't tell me shut up, I tell you shut up!
[Lino hears another line beeping, and sees the Caller ID revealing to be Luca.]
Luca(not even realizing that he accidentally dialed the wrong number): Hi, how you doing? I'd like a large pie, everything on it: anchovies, meatballs, mushrooms...
Luca: Oh, uh, hi, Boss. What're you doing at the pizza joint??
Lino(getting frustrated by the octopus's clumsiness by now): GET OFF THE PHONE!!
Luca(whining): But I'm hungry.
[Lino rolls his eyes and hung up with Luca, still irritated, and continue yelling at Oscar through the phone.]
Luca is a blue-green 8-legged octopus with a big head.
