“Take me to your traffic light, foolish Earth cupcakes!”
The Space Alien wants to conquer the planet, but it keeps getting sidetracked by interesting tourist attractions, so it hasn’t really gotten around to the whole taking-over-the-world thing yet. It’s also not sure what to do with the Earth once it’s been conquered, but it’s pretty sure that whatever it is, it’ll be totally awesome!
