1st area - Rabbies - These sonuva will attack you relentlessly without mercy. Many good noobs were lost to these soulless killing machines.
2nd area - Boars.... dem boars. Ridiculously fast attack animations for such a fat creature. This is multiplied 10 folds when it's an elite and 100 folds when there is more than one boar in a room. I still have nightmares of being in a room with 5 elite boars. Someone save me.
3rd area - Rather than any one creature, it's the combinations. We have the fast jumpkins, which are easily dealt with using quick swings in front of you. BUT if theres a scarecrow mixed in, NOPE. You can't stun scarecrows and they will destroy you. One swing from them opens up many attacking opportunities for jumpkins as well. Okay, so you'll just kite, right? Good luck, since a halloweed has burrowed and is on it's way to destroying your behind. Guess you'll just have to block the halloweed's burrow attack right? HA, 3 lantern jacks have already surrounded you and are firing from all directions... I hate the pumpkin woods T-T.
4th area - Wisps, by a long shot. You wanna hit me? I'm over here~! HEY DON'T IGNORE ME! *Fires homing pellet* Haha! Now come hit me! That's right, closer, closer.... NOPE! FULL RETREAAAAAT~!
