Make it so we can tame the birds that attack us and keep them as pets. One per player.
-Have birds spawn with different colors (some rarer than others).
-Activate NPC to have it follow you and possibly rest on your head or shoulder.
-Used as a quest mechanic in the future?
Maybe:
-Have them pick up items off the ground for you?
-Have them auto-attack NPCs for 0.5 damage?
So many cute things can be done.
