Chara has a show ran by MTT Network where she just does..... stuff.

97% of the underground watches the show daily making her the most popular person in the underground.

Papyrus co-stars every now and then.

(sans would too but he has a lot of stuff to do)

Papyrus and sans are also pretty popular as they go around either goofing around or helping do tasks.

Mettaton has his own show, but he is more worried about Chara's due to them being pretty close.

(I made her in her mid 20's for reasons I think obvious)

Wad the only surviving Dremurr child

She also is the lead singer in a band with sans and Papyrus, which performs weekly.

Nabstablook is a magician just putting that out there.

Mad Dummy works at the MTT shop

Frisk has a cooking show with Mettaton, Chara and sans

Sans loves cooking so he'll make sure he can be there.
