EarRape: Make the creeper Climax(if you have done it before just do it again, she has a new VFX, and thats what gives the achivement)
Fireworks: just penetrate the mobs behind with the firework and light it up
Halloween ritual: Just do the halloween update content an collect the 6 new characters
No-clip: Craft the enderbeats and use it on the kitty or the behind of any mob and quickly before the beats pop out use the piston to push them all the way in, do this 4 or 5 times and you should get the achivement and a new map (you have to use the enderbeats specificaly, the new beats of the halloween update does not work)
Return to sender(the chinise text one): Unlock the endergal and buy the 20 emerald chinise bundel(the "yellow" box) put the endergal on the Box Boat you unlock and make her climax until you get teleported to the new map
Head swap: After completing Halloween ritual do the ritual again with any character that is not (Sheep, Bee, Pumpkin or Endergal)
