Porki

About
Porkis are one of the most annoying creatures. Although they don't hunt or chase the player, their spiky prickles keep anyone from hurting them, making them unbeatable. Although not normally dangerous, they can easily catch a player off guard if he's not watching where he's going.

Attack
The Porki will damage you on touch.

Drops
Porkis can be killed only attacking from ahead. On death Porkis do not drop nothing.
