ThE IncrIDIbl mOIl-Tem!111!!1

Okay, this... is a 5 minute doodle. But I'm gonna share this because this is... my idea of an Undertale AU character that hasn't been done before.
So this is the Mail-Temmie, the interdimensional delivery Tem, or Moil.
She just basically delivers Mail from AU to AU whenever it is needed. 
So yeah, she's an Out!Code, as some may refer to, as she travels between the Universes.
She is your standard Temmie in personality but happens to pop up right in front of you when you expect it the least to deliver mail.
She's not really a protagonist, but I think she can serve nicely as a side-character. I'm not good in writing characters sooo... I'm fine with this xD
