Fish exclusively at Walrus Way until you have your Bear Acuda. By then- your bank should be full of jellybeans. The Brrrgh is definitely the best place to fish. Big fish (worth big jellybeans) and narrow ponds make this winter wonderland a must for any serious fishertoon.
Then go to Minnie's Melodyland and get those Piano Tuna's. Save the easy fish for last. And don't be in any big hurry. From what you've described, I'd say you need to fish a minimum of 500 more buckets before you get the rest of your fish.
I've fished over a 1000 trying to get Full Moon and Allstar. Anyway- GOOD LUCK and remember to turn and reposition every two hours.
