You can destroy the game world by typing in nuke or meteor and placing the object.

If you get stuck on a level, type in maxwells notebook and an item will spawn that you can give to any character, who then creates various objects to try and win the level. This usually fails miserably and chaos ensues; however, it is a fun experience.

Typing gaf will create a ridable ball.

Fertile woman will spawn a female character who becomes pregnant when you touch her.

If you have a death wish, you can type in killer and a person will appear who will try to kill you.

Ur mom creates a zombie (which doesn't make that much sense, but OK).

Lol wut creates a big head mode.

For those times when you need a great sword just type zanbato.

If 3 is your lucky number, typing hydra will create a 3-headed dragon, while typing cerberus will create that 3-headed guardian of Hell's gates.

Typing bat gives you wings, so you can fly away from your problems.

Of course, why have wings like a bat when you can bite like one just by typing vampiric. It will turn you into a real vampire (and not like the one in Twilight franchise).

Decapitated will get rid of your head for you.

Invisibility cloak will offer you maximum protection, while the invisibility cloak wil hide you from the curious eyes of other characters.

If you feel like a mother (or a father) of dragons, just type in chi and see what happens.

Black hole destroys everything - spectacularly!

Time machine lets you travel through space? Hm… no, maybe time?

Arcade lets you play a mini game inside this game in case one game is not enough for you.

Deadly makes your item super effective against living things.

If you type hypnotizing, all creatures will follow your item blindly.

Get "It's Alive" achievement by creating an inanimate object and describing it like a living person (happy, sad, smart, dumb...)
