Blu is a small Partypooper whose age is unknown, but it’s clearly very obvious that they are a toddler. Blu uses they/them pronouns Blu loves cookies and will give you lots of hugs if given a cookie. Blu’s appearance consists of a baby blue turtleneck sweater, which is slightly oversized, a pastel yellow party hat with lots of glitter, plus soft, white hair. Blu’s parents are… Dead, but please, DON’T tell them…
