In an attempt to set a spooky scene for Happy Pets, CrowdStar has done it in the only way it knows: more pets, of course. With Vampire Pets that transform depending on the time of day (go ahead, you guess when), the studio might have outdone themselves when it comes to nifty-looking pets to show off. As per usual, there are limited quantities of these rare pets and they each range from 56 to 68 Facebook Credits, or $5.60 to $6.80, respectively. Here's a full list of the vampiric critters you can buy:

• Vampire Triceratops: 56 Facebook Credits, matures in 14 days, feed every 21 hours
• Vampire Dog: 58 Facebook Credits, matures in four days, feed every 12 hours
• Vampire Bear: 58 Facebook Credits, matures in seven days, feed every 16 hours
• Vampire Unicorn: 68 Facebook Credits, matures in seven days, feed every 16 hours
• Vampire Dragon: 68 Facebook Credits, matures in 14 days, feed every 21 hours
• Vampire Cat: 62 Facebook Credits, mature in three days, feed every eight hours

Watching them change from a pathetically pale cream color to a deep black with spots of crimson red (and the eyes!) is actually somewhat off-putting. Oddly enough, during any other season that would be considered an insult.
