But not the Pokémon city.
I didn't make those fishing pole parts up, by the way.
I always found Animal Crossing's gold fishing rod and bug net kinda pointless, since you only get them after you've caught every type of fish or insect. Sure, you'll probably do a little fishing or bug hunting afterward, but not enough to reap the benefits that either golden tool gives you. Maybe if you'd get them after filling, say, 75% of either encyclopedia, then you could use them to catch those last few hard to find/catch fish and bugs. At least City Folk let's you find silver versions earlier on.
Maybe the upcoming 3DS version will alleviate this problem. But it almost certainly won't.
