At Walmart, I found Doctor Dreadful Aliens Candy Making kit is only $20 with a $10 Mail In Rebate form right on the box.  That makes this only $10 after the rebate.

The Doctor Dreadful Alien Autopsy is the doctor’s most disgusting & tasty experiments yet. Make tasty eyes, inject lung bugs, & watch guts come to life. Make some disgusting food and gross out your friends!

Amazon has Exclusive Doctor Dreadful Aliens for $36.95.
