Adding an item drop in monsters that you can exchange for christmas present would be cool, it would promote hunting aswell.
Just like this:
monster have a possibility to drop 1-3? of this item.
An npc will charge;
5+ of this item for a small prize (suggesting some dollars or pokeballs)
25+ of this item for a medium prize (suggesting an evolution stone)
50-100+ of this item for a big prize (suggesting a boost stone or masterball)
250-500+ (suggesting teleport to island with normally unaccessable pokemons)
The suggested prizes are ofcourse depending on what droprate the items in question have.
There's an odd bug where if you fix your pokeball while riding something, you can switch it out and when you use order on yourself it'll pop out that pokemon. Doing this you can use pokemon that your level can't use, and some of the moves work (I used Tauros, then switched to Onix and could use his first 2 moves even though I'm level 41 )
