Millie is a kleptomaniac. She gets a rush from stealing extremely petty things. The things she steals are items people won't realize are missing and, if they do, it'll be a minor inconvenience at most. She gained her orange color from the first thing she stole. A fellow classmate had an orange pen she wanted, so she snuck it into her pocket when the classmate was away. She still has it to this day. Even though the items she steals are petty and worthless... she still takes great pride in them.

Pen island

• I always imagined the pen she stole as just like an orange cheap papermate inkjoy pen. Mostly cause I own one and I thought it would be if someone went out of their way to steal it since they cost like 65 cents each.
