Mammon was dared into him dressing up in cat ears and a cat tail. He did so reluctantly, "Ughhh...why do I have to do this..?" he asked himself as he put the ears and tail on, the brothers laughed at him and even Lucifer chuckled a little. Mammon glared at all of them until he had an idea. He walked into your room to see you on you or bed, he grinned before sitting on your bed and nuzzling you with his head, letting out a soft purr.
