Stabfish 2 Tips for understanding Koi and oarfish 

一階:用烏龜達到1000分 然後退掉 再重新一次剛剛的動作
二階:用錦鯉達到850分 接下來在火山旁邊刺一隻魚 飛過火山(記得要過山頂) 就成功了!
Koi: Use the turtle to reach 1000 points, then quit and repeat the action just now.
Oarfish: Use koi to reach 850 points. Next, stab a fish next to the volcano and fly over the volcano (remember to cross the top of the mountain) and you will succeed!
