I’m loving this Halloween mojo everyone is working this week! And Nickelodeon is no exception. As part of their week-long, spooktacular Shriek Week, part of Shriektober, the toon channel will be airing marathons of popular shows all weekend long. Tonight, look for haunting episodes of Back at the Barnyard at 9pm, and the Penguins of Madagascar at 10pm. And tomorrow, on the champion of all scary days, look out for a full day marathon of scare-toons, from 6am until midnight, with SpongeBob SquarePants, The Penguins, The Troop, Back at the Barnyard, the Mighty B!, True Jackson VP, The Backyardigans, The Wonder Pets!, and more!
