A planet in AH.com Wars. The equivalent of Hoth from Star Wars, the joke being that it was ironic that such an icy planet was called hot-h and so in AH.com Wars it becomes the more appropriate cold-h.
Inhabited by penguins and sealions, who prey on the former. Site of a battle between Imperial and Rebel forces in Episode 5.
Incredibly annoyingly, this joke was stolen (along with Thai fighters) by the Family Guy writers. Cue P-rant.
