[James and the Giant Peach] Why did a rhino eat James's parents?

Are they carnivorous in this universe? Was it just this particular rhino that decided that plants were no longer enough?

I don't think it was really an actual rhino.

James and his parents were at the beach watching clouds and picking out shapes when a sudden storm rolled up on them. James thought the thunderhead looked like a charging rhino. 

The rhino eating his parents was simply the storm's winds sucking them up or sweeping them out to sea. James, being a small child, thinks the Rhino 'ate' them. James' aunts are cruel enough to tell him that's true, and that every thunderstorm is the rhino coming back to get him, so James sees every thundercloud as a rhino from that point forward. It's a projection of his inner fears.

Alternatively, James's parents probably weren't actually eaten by a rhino, instead they likely died in some sort of run of the mill tragedy. James was probably young enough that he misremembered the accident - maybe they'd just gone to the zoo and seen the rhinos, or they'd read about rhinos.

A vehicular accident seems very likely, especially a train, given the sparks and sound effects that accompany the rhino's appearances in the movie, and the way it seems to spew black smoke like a smokestack. James' aunts, being cruel, nasty people, went along with the rhino story to torment and terrify little James.

Or maybe a rhino really did escape from the zoo and killed his parents, and his aunt's, again being cruel and nasty human beings, told him it ate them to scare him.
