It could be interesting assuming somebody steps up do the plate and makes an awesome plot.
On another note, it could be a winter RP. That way you can include all nationalities and cultures December-ish holidays.
Lets just try and avoid this one:
ELF: Oh no. Where is santa?
DELIBIRD: Arg. I replaced santa. Fish for all.
CHILDREN: Oh no! *DEATH*
(Unless you are into that. More power to ya.)
But I digress. Would this be a Pokemon RP, or some other universe?
