They're not pukeberries, they're bukeperries.

Just ignore them if you don't like them? I like to toss them in the ocean or a river, to feed necks.

I doubt I'll ever use them, except maybe for the over-the-top visual effect (it's gross but hilarious), but the things have been a HUGE source of entertainment for my friends and me in multiplayer (no consuming them is involved).

Bukeperries were a great addition, imo.
