How the F**k does Ducky know this

[Bruton the Iguanodon]

When Ducky says, "It is very special, his mother gave it to him" how does she even know about his mother? Littlefoot could have told her but for some reason he didn't. One would reasonably assume he was still too sad to talk about her. But strangely he says quite cheerfully "My mother said it's where all the herds are going" as if he was talking about something his teacher said earlier at school. So obviously he was at the point where he could talk about her and without the threat of the taps being turned on. But in the short time they were together before they met Petrie he didn't. So what happened? Did Littlefoot ever tell his friends about his mother, even?  :huh:

You know, they've been on the way for a while. He probably told her what happened to his family and all he knows about them, including the present of his mother. They might have been walking for days for all you know, they just skipped some scenes until they were at Petrie's tree.
