Well you obtained the code/the actual event, so to me, they are your pokemon not the person who RNG'd them. That's the reason I said I would do a BP--I let people have redist-rights on them (like the Gligar I did for Diabolico).
Would you not even accept credits for the Treecko (I can do any future BPs you want/need)? Sorry if I seem persistent but yours is the only DW Treecko I've managed to come across. ;_;
