Henesys.. wtf?

I just got un-banned and it was finally official, I use @go henesys and then I walk to the left and a spiky thing does 2k dmg to me and kills me. It is hided behind the Maple T.V so I don`t know what monster it is but it reminds me of an enlarged version of the things that Papulatus spawns. I don`t know if there was a Summon Event or if this is result of someone hacking but please solve it and clear it.

hmm. ill look into it.

Happened to me too, to dodge it just jump on the higher platform above Cody (In henesys) and then jump over it towards the portal to get to Henesys Hunting Grounds1.
It is the thing that the Pianus spawns, not the pap (Pap spawns the small ones, Pianus spawns the big spikey ones that don't move).
If it was the pap's spawn, it would've died once you got killed/hit by it.
