Trade Spearow
You can find a little girl in the house next door to the Fan Club who wants to trade a Spearow for a.

Many Important Items
Convince the old man in the building left of the Pokémon Center that you love fishing as much as he does and he'll take a shine to you. He will give you his Old Rod as a gift! Now you can use it near any body of water and get... a. Or... another Magikarp. Yes, that's all this Rod catches. Good news if you didn't buy one earlier.

Something slightly cooler than the Magikarp Stick can be found at the Pokémon Fan Club, located directly above the gym. Listen to the president's boring story and he'll give you his Bike Voucher. Redeem it at the Bike Shop in Cerulean City, and you'll get a Bicycle you can use anywhere!

Also, you can talk to the girl standing next to the counter for maybe an even more useful item: the VS Seeker! This little gizmo allows you to re-battle trainers you've already fought before... if they're feeling up to it. Most of the time, the trainers have prepared for your coming, and have their team at a higher level than before, so watch out! To use this contraption, select it from the Key Items menu, and activate it. This has a limited battery life, so you need to walk 100 steps to recharge it. A great item for heavy trainers.

Anne Ticket from Bill, Head Over to S.S. Anne for some well needed training to fight the Lightning American.Lt. Surge will be using Electric Pokémon so Any Water or Flying Pokemon you send out against him are going to be fried, especially from his supercharged. It's highly suggested that you grab one of the ever-abundant before going on to S.S. Anne. you can get them from Diglett's Cave. When your feel ready to fight for your third badge, after getting Hm01 (Cut) from the S.S. Anne captain. Use it on a Pokemon that's not a major team member, since you can't take out HM moves until a long time from now (so don't teach or  Cut, please). When that's all sorted out, use cut from the Pokemon you taught it to (make sure its in your party), and proceed to challenge Lt. Surge.
