You were walking down the street and as you look to the other side, you see people. H.H(Halloween Herson) looks like a 17-18 year old, C.C(Carson/Christmas Cerson) looks like an 18-19 year old, and P.P(Party Person) looks like a 20-21 year old. Those are their ages and yet they still look and dress very childish. H.H is halloween themed carrying candy around, C.C is christmas themed, still wearing his pjamas and drinking his hot coca, and P.P is wearing a party hat

Halloween Herson/Hersan: "Are you sure we're going the right way to the diner?"

Party Person/Partsen: "Of course!! Uhh... I THINK."

Christmas Cerson/Carson: "Can't believe you two just forced me to go out when I just woke up.."

They all seem like siblings. H.H(Halloween Herson) is a girl/sister, C.C(Christmas Cerson) is a boy/brother and... P.P(Party Person)'s gender looks unknown..

Js use 'H.H' 'C.C' 'P.P' or 'Hersan' 'Carson' 'Partsen' for short if you're lazy at typing
