Info from Licensor: "Storm is a female Eastern Grey Kangaroo. Unbeknownst to many, female kangaroos also like to practise their sparring skills, either with males or other females. In this video, Storm is on the right and ends up on the left. She is practising with Venus, who is taller but a few months younger. Both girls were orphaned and bought up at Wild 2 Free Kangaroo Sanctuary, where they're now released."
