The overpass used as a background in "Be Careful What You Wish For..." was used again as a background in this episode behind Skipper when he is looking towards the Masked Mutant's headquarters.
Skipper spots the Masked Mutant's headquarters the first time he goes past. He then goes back the next day, and the headquarters have vanished. He then goes back a third time, and the headquarters aren't there yet again. However Skipper says "How can it be. It was right here yesterday," although it wasn't.
The bus which Skipper keeps catching to go to the headquarters has Goosebumps written on it. Adverts on the side of the bus, saying "two thumbs up." This is a reference to the television and book series.
Skipper: The Masked Mutant is the most evil comic book villain there is.
Libby: (To Skipper) What do you collect? All that superhero junk like the Masked Mutant? Skipper: Yeah, I know everything about the mutant. He is the most evil supervillain of them all.
Libby: You really think a comic book character could come to life? That's sad, that's really sad. Skipper: Don't make me cry.
Dan Warry Smith (Skipper Mathews) played as Seth Gold in the season 3 episode, "Click".
Based on Book #25.
