Pokemon dilemma...

So it is currently 3:20AM and I've been struggling to fight a gym leader in Pokemon White for a good hour or so. Felt like I should blog about it. Firstly, yes, it is very early in the morning and I am delusional. The following blog entry may not even make sense, but I'll be sure to check what I wrote tomorrow morning. So first thing is first. The way I play Pokemon games is that, I train a single Pokemon (usually my starter) all the way and not worry about any others. My dilemma is that this one gym leader uses a grass type Pokemon, and it's razor leaf kills me every time. So I went into a forest nearby to see if I could find any bug/poison types. Luckily, I found a Fushide (bug/poison type) and caught it. Now the problem is that training it up won't be easy. The only way I could level it up is to grind on nearby wild grass types, and I'd need to get this Pokemon to at least level 22 before I can properly use it in a battle. Currently it's level 16 and I have no idea how long it will take to get it up 6 levels (22 - 16 = 6? I dunno, I'm starting to see 2s in binary codes ._.). Well, good thing tomorrow's a day off, I'll spend my whole day working on my PKMN 2 KICK THAT GYM LEDAR ASS!!!! IMA STOP HERE SINCE IM STARTING TO TYPE IN CAPS LOCK OK BB.
