Polkips enjoy collecting shoes, shiney objects, dead animals, and running around with them in their hands screaming and showing them to people.
Often on first impressions quite insular and anti-social, it usually only takes a handful of glitter to win them over.
Be warned, they have a tendancy to hold grudges for a very long time if you rub them up the wrong way.
"what the f*** was that?!"
"That, my good man, was a Polkip."
