In round 1 I participated in:
A biker gang of about 8-9 people at it's peak


A "wardrobe malfunction" using this slot and someone else using the new underwear hat.


and lastly a pirate and his rum


Had no luck In any of those but I partnered up with someone new in round two as frisk & chara from undertale and got lucky in the first draw.

Only played 5 minutes of undertale in my entire life so I didn't really get it but I managed to edit together that head and the shields in a few minutes so haha
