The Leptoceratops in the I'm A Dinosaur video is destructive and likes to show off her muscles. That is quite okay, because it is probably fairly accurate to state that Leptoceratops was a strong ceratopsian.
That strength of the animal is not expressly mentioned in either the Enchanted Learning or KidsDinos fact pages. It is also not exemplified in either the accurate or inaccurate scientific illustrations that could be used for coloring or as visual guides for drawing your own Leptoceratops to color. Remember, if you use these to color ask permission before you try to post your artwork online!
