I was on a server with factions and stuff (this one was actually fun- griefing is allowed so you gotta hide stuff) And i found a huge mountain, PERFECT for the PEERRFEECT house. i go inside, build a gigantic staircase leading to the top, come back down, begin to switch out walls with cobble to make it prettier, open a 1x1 hole, 3 creepers drop in, forget. good thing i got coords tho
