Tunnel of Terror

Plot

 * The title "Tunnel of Terror" is likely a tribute to the Simpsons "Treehouse of Horror" series involving the telling of horror stories depicted using the cast, which is what happens here.
 * Thunk's tale about dating a monster (a bat shapeshifted into Blurg Brood) is a tribute to the book/film series Twilight.
 * initially her comments about "juicing" cavepeople seems like an attempt to get around the censors (not using violent language) but then later Handsy when referencing an exsanguinated Bow Chicka Wow Wow says that she killed his boyfriend by drinking his blood.
 * Eep's tale about a murderer includes a classic spin of accidentally killing the wrong person who was not the 'mad smasher', a common trope/misdirect.
 * Amber smashing through a tree and sticking her head through to shout "Here's me!" is a reference to Stephen King's "The Shining" where the murderer shouts "Here's Johnny!" made famous by Jack Nicholson.
 * At the end, Thunk spots a painting of Shrek and Donkey. They all run away screaming when they see it.
