Thought you'd like that one:) I'm tempted to write that one too but it'd be really short and silly and pointless, and surely someone's thought of it before...

I'd really love to see someone do that Zazie one someday. Everyone in the trigun fandom seems to write AU's where Wolfwood didn't *spoiler*, but honestly, why not change another event and run from there?

Saiyuki challenges

The Sanzo-ikku gets very very lost when Hakkai's only map is accidently eaten by Goku. Three days of forced companionship later, everyone's sanity is hanging by a thread... and Goku is hungry.

Inu yasha

Myouga introduces his nephew to the life of a flea youkai by taking him around the country to "meet" ie. taste, different youkai. They must visit Inuyasha, Kouga and Sesshoumaru at least.

Inu yasha discovers he can use spiritual powers (like kagome's) but only on the new moon.
