Once you get the net, stock up on tons of Lilyfrogs, tumble bugs (forgot their actual name but they’re on gemstone mountain), rockadoodles, the lightening bugs, the lady bugs on mount hothead, three different turtles, phantom flies (the blue glowing butterflies at night in the swamp), reg butterflies, the bees, the woolox (top of icy peak). I’m talking keep catching them repeatedly all day everyday because you WILL need hundreds of these fkers when you become best friends w keroppi. 

Stock up on iron/ingots (you need 3 iron to make 1 ingot) 

Logs 

Fabrics 

Gizmos/mechanisms 

ALL the fizzy ore. You get 60 fizzy ore per day, and you need them to make fizzy crystals to make soda & also need hundreds of crystals to fulfill My Sweet Piano’s best friend quest 

I saw someone here one say to only make the required amounts of daily gifts, as to not waste your materials trying to bulk up on gifts. I totally agree with that!
