Brachiosaurus nibble - Walking With Dinosaurs
Brachiosaurus from Walking With Dinosaurs, where the little one comes out early and is big itself. Only when does the mother follow shortly after that its scale is totally shot out of the muddy swamp waters.
Both get about for a while nibbling on the balloon foilage of the plant-life in the stadium of Acer Arena.
