Eerie, Indiana: The Other Dimension (1998)

The series revolves around best friends Mitchell Taylor and Stanley Hope. Like earlier Eerie, Indiana, residents Marshall Teller and Simon Holmes and they are constantly encountering strange and out-of-this-world phenomena in their hometown. Helping out in their adventures is the mysterious local bartender, Mr. Crawford. The show is technically a spin-off of "Eerie, Indiana" (1991), since it takes place in a parallel universe Eerie that gets "infected" by weirdness when a villain opens a portal from the original Eerie to this one in the first episode of this show.
