This is the amusing a moment a tortoise called Michelangelo did battle with his own reflection in a mirror.
Although he was named after the famous Ninja Turtle, this fight scene featured no nunchuks or wise-cracks - just some rather inexpert biting of the glass.
This Michelangelo isn't a teenager either; he's thought to be between three and five years old, although his owners aren't completely sure because he was found roaming the streets of Chorley, Lancashire in the UK.
