Odd della Robbia of Code Lyoko...as Oddish, the Pokémon.

I know that January isn't the right month for Halloween stuff...but I'd probably have forgotten about this pun by October...and it's kind of too stupid to be worth jotting down...

Of course, if Odd is odd all year (and he doesn't have any other choice) being only odd-ish on Halloween would actually make him less odd than normal. But that kind of works, since Halloween is probably the only holiday that could make Odd appear less odd than he usually does...
