Hi, just joined the game, and dropped a $10 donation to start the game off right. Never knew anything about Pokemon before Pokemon Go, wanted to try an actual game that didn't involve catching 600 pidgeys to gain a level :P
Question:
I want to headbutt these trees, but I only have a level 10 Pikachu that I gave headbutt. Apparently he isn't happy enough. How do I raise his happiness ? Or is this just something that you do much later in the game ?
