The wood fish is one of the most elusive and difficult fish to catch.You really need a Gold fishing rod and level 3 fishing experience if you want a good chance of catching one.It lives in the Harvets Goddess Spring and can't be found there during the day.
NOTE:this is the only way to get it because no animal will give it to you when it reaches 4 hearts!
(But you can get a suary from all 3 cats at 4 hearts)

During spring,buy alot of happy fertilizer and strawberry seeds.plant as many seeds as you can.then use the fertilizer on the plants.the fertilizer makes healthy plants and makes them grow faster.you can make over 50,000 G a season!even better!the strawberries can also grow through summer!when fall comes,you will have a very,very,VERY large amount!

Hit a rock with any strenth hit a nd then a level 3 hit
