You worked late last night, and when you returned home, you found that your house had been broken into–the door was wide open. No one had turned on the house light, so it was dark in the house

When you entered the house, entered your room and turned on the light, you found there a 1-meter anthropomorphic red echidna with a horizontal white stripe on the top of its chest. He looked at you with his purple eyes and stood in a fighting pose, clenching his fists and holding them out in front of him, asking in his deep, low and cold voice, starting to get angry

"What are you doing in my house?"
