First, head down to the Dance room in the Apocalypse Temple and go through to the new room on the right. Place a Pygmy on the weird electric-shock thingymabob on the left and tap it twice. Swipe the closet as far to the right as possible, and you should be able to pull a pygmy called Tom out. (This guy is the bringer of the Apocalypse, and is very slightly insane in the membrane.) Go to the Time Chamber and turn another Pygmy (not Tom) into a baby, then go outside. When the clock opens, go inside. In that room, drop the baby into Tom's hands, and the baby will turn into the evil alien god Xenu. (At this point, you can kill Tom if you really want to.) Put a Pygmy into his left or right tentacle, and a black gem should drop down. Go back into the Temple and do these six things:
1: Put a Pygmy on the Time Pedestal.
2: Make the Queen Bug eat a Pygmy.
3: Put a Pygmy in the gogo cage.
4: Infect a Pygmy.
5: Cleanse a Pygmy.
6: Put a Pygmy on the electric-shock thingymabob.
After doing all of that, you should have seven gems. If not, try again. Go outside and put the gems on their respective pedestals, which shouldn't be hard to figure out. When all seven gems are in place, the clock will shut and Xenu will be trapped. (Kind of like the seven Chaos Emeralds for Sonic.) A female Pygmy named Sun (from Pocket God Comics) will come along, and will say 'Hi guys, what's up?' However, Xenu's tentacle will reach out and grab her, taking her away. (Kind of like King Kong.) Other achievements needed to get the Idol can be done by messing around with Tom, Xenu, the gems and the weird little red thingies. Hope this helps.
