How would you protect your planet?

[Ginga]

An army of mericiless, acidic cheese-flinging, phaser rifle-toting ROBOTS! ...KITTY ROBOTS!

*gasp* *points to sig* And the robots would look like THAT kitty! And they'd EAT people who called 'em gerbils! Then they'd all say the Zeeky words and DESTROY THE WORLD! BWHAHAH!

...oh... we're trying to PROTECT the planet? Ohhh...

Okay, so the sig kitty robots won't say the Zeeky words, but they will eat people, have giant phaser rifles, and they will fling acidic cheese.

And that's how I'd protect my planet. ^_^
