I headed over to Four Island in order to pick up some Pokemon from the Day Care Center. I went to Icefall Cave afterwards to capture some Pokemon and then I left and I sailed back to mainland Kanto on the Seagallop ferry. I decided to train my Pokemon some more so I flew to Cerulean City and I went to Cerulean Cave since there were tons of powerful Pokemon inside that I could battle against to level up my team. I entered the cavern and I trained for about 30 minutes inside before I had to leave in order to heal my Pokemon. I went back to train after that and then I went around Kanto and I used the VS Seeker to re-battle some trainers on various routes. I continued training like that and I eventually headed back to Five Island in order to train there some more. I went island hoping after that and I trained on Six and Seven Island as well before saving the game on Three Island.
