Ammon News - A widely circulated video documented a daring encounter between a tiny deer and an enormous rhinoceros.

In wild video footage, the little, brave muntjac deer dared to challenge the 1.7-ton rhino – named Maruśka – with no hesitation.

The unlikely sparring partners clashed in the snow at Wrocław Zoo in Poland.

At the beginning of the clash, Maruśka nodded her head up and down twice, in a move that would daunt even the bravest of hearts.

Despite punching well above his weight, the pint-sized male deer took the challenge and charged without hesitation.

Catapulting himself front-on, the deer and Maruśka knocked heads before backing up from each other.

Preparing for the second round, the deer observed the rhino, while Maruśka jumped excitedly between her front legs.

The pair lightly bump heads again before edging away from each other.

In their third round, the video shows Maruśka faking out of a colossal head-bang, making it seem as though the two are playfighting.

Throughout the entire encounter, the deer does not shy away from the confrontation once.

The footage was posted to social media by zoo staff, with the caption “Someone forgot to look in the mirror this morning!”
