[Mettaton's happy to follow Asriel in, and honestly, he's impressed with how nice it looks. It's well-outfitted, and although Mettaton doesn't really need a bed, the token comforts are still a kind gesture.]

You've done a great job in here! Definitely worthy of a break!!

[So saying, he finds himself a nice spot to sit among the blankets.]

Have you, ah. Have you been in here all day? You've done enough, you know. It's cozy and positively exudes preparedness!
