ZERO?! ZERRRRRRRRRRRRRRROOOOOOOOOOOOOOOO? NIGHTMARE BEFORE CHRISTMAS?!!?!? O____O

-AHEM- Okay. In all seriousness.

1) Zero wants a bone ;; Ghosts? Ghost animals? NIGHTMAREBEFORECHRISTMAS! xDD;
2) Green skies, head for shelter ;; NO idea with this one. Its said when you see green skies, theres a Tornado afoot.. but... Hmm..
3) Third Rock from the Sun ;; All I can think of is "Earth". And the show. Which dealt with aliens.
