Why can't I stop talking to my turtle Sammy the Sprinkler?

He's possessed by the all-mighty Stan. He makes me do sacrifices to Satan, especially my cat Chuckles. I don't know why he hates Chuckles so much. He keeps telling me to do bad things... I don't know why. He told me to kill the white man and to eat plenty of gay goldfish (ya know the rainbow ones). He also tells me to make out with plenty of girls for Mac 'n' Cheese. He says if I don't meet his demands he will kill my entire family. Please help! (If possible call 911. My address is P. Sherman 42 Wallaby Way, Sydney, Australia)
