In Emerald, I recently completed the Hoenn Dex... and chose Cyndaquil as my reward, naturally...
It's now at Level 26, but yeah... that isn't really that exciting.
There's absolutely nothing interesting happening in my Fire Red game. My Pikachu just grew above Level 30, but since it wasn't traded, it still obeys me.
I also recently started a Gold game, and I'm trying to train my Pokemon to beat Whitney. I can't stand her Miltank, frankly. Only one of my Pokemon is immune to Miltank's Attract (my Quilava, which happens to be female... the rest of my Pokemon are guys), and that one Pokemon is also weak against Rollout... so I'm depending on a good level advantage to win.
And... I tried out Berry Crush for the first time last night using my Emerald game and my sister's Leaf Green game. I'm saving up the powder for PP Ups (they take 3000 units of powder each and I only have slightly over 1400...)
