Hello and welcome!
You mean tips as in how to eran food? I think a good way to start would be to get one of the free starter Knuffel from Knufftropolis.

You can feed and play with it to level it and each 10 levels you get food and you can also dig with it on Candy Island and it can find doof, material and items for you.

And a really fast way to earn food would be to play the games. There aren't many, but you can earn up to 1000 food in one day by playing them.
