I love Mike Sterling‘s kiddie version of Alien:
“BOO!” shouted the Alien, and Ripley cried out in surprise.“That wasn’t a very nice thing to do!” Ripley scolded, shaking her finger at the Alien. “You really scared me!”
“Gosh,” said the Alien. “I was just trying to have a little fun. I didn’t mean to really frighten you!” The Alien looked sad.
More — though not nearly enough — here.
