Here more of Tom getting friendly with Chomper.

Tom: So Chomper tell me, how did you make friends with planet eaters?
Chomper: Oh it's a long story, but Littlefoot and the other hatched me, and tired to teach me to be a good Sharptooth or... What was it humans call me again?
Tom: A T-rex. You know Chomper, your actually my favourite meat eating dinosaur. And I never thought they'd be soo cute as youngsters.
*Chomper blushes and Tom picks him up*
Chomper: And I'm starting to like you Tom, you certainly smell friendly.
Then Petrie come along and lands on Tom's head. And unlike Littlefoot in the first film, Tom isn't too fussed about it.

Tom: hey carful up there Petrie *laughs*
Petrie feels Tom's blonde hair.

Petrie: Hmm. You humans got nice soft heads Tom. What is this fuzzy soft stuff on your head?
Tom: It's called hair Petrie, it grows on our heads to keep them warm.
