During trick or treating, Angelica is in a leading line with 3 other kids. But when Drew is heard off-screen giving them their Reptar bars, he says "One for you, for you, and you Wolfie, and one for the little mummy," as if there were four other kids with Angelica instead of three.
After the babies are screaming to try getting Reptar bars, when Didi tells Stu the babies were scared from the trick or treaters, a picture randomly shakes up and down.
