Undercure! Monster Kid

For -Undercure- / Madiku_Galaxy
So I kinda have an idea
Monster Kid had his arms before Chara/Frisk came but then they began to melt off, to the point where they're totally off now and Monster Kid is always very sick (compare to the other monsters) but then (like you said) would always want to fight alongside Undyne for the cure
