U read the title xddddd 

So yea I kinda decided to change the ages of Papyrus and Sans cuz I wanted Papyrus to start his "training" at 15 like the TMNT 2012 turtles xdddd And that would lead him to one year of training when Frisk came and that means Sans is 17 

So here r the confirmed ages for my fanfic (probably coming out today or tomorrow)

Flowey: 26
Frisk: 16
Chara: 15
Asriel: 14
Toriel: 50
Sans: 17
Papyrus: 16
Tim (Monster Kid): 13
Temmie: 18
Undyne: 28
Alphys: 31
Mettaton: Well he's a robot but I guess it's 26
Muffet: 35
Asgore: 52

Aight so these r the final ages I swear I won't change it again

But hey it worked out for my ship sooooo
