Os presento algunas de las ideas que me ha dado:
Your challenge is to write crossover fanfiction combining Sonic the Hedgehog and Buffy the Vampire Slayer. The story should use creepy interent fetishes as a plot device!
Empezamos bien... Sonic, Buffy, ¿fechites escalofríantes de internet?... Oye, hasta puede funcionar.
Your challenge is to write crossover fanfiction combining Elite Beat Agents and Captain Planet. The story should use becoming the President
as a plot device!
¡Suena genial! 
Your challenge is to write crossover fanfiction combining Yoshi's Island and 4chan. The story should use religion as a plot device!
... Eh... no. Porfa... no.
Your challenge is to write crossover fanfiction combining Donkey Kong and CSI. The story should use anal sex as a plot device!
¡¡¡¡AAAAAAAAAAAAAAHHHHHHHHHHHHHH!!!!
