How to get more food for your Tama? (Paradise)

Hi! My Tama just evolved into a kid, and I wanted to feed them only shrimp, but you only have 3 doses of it and then it runs out. I checked the store and you need Planet Level 5 to even buy food, and you can only do the Egg Hunt once a day for random stuff... Do you just kinda deal with it until you hit level 5? Cheers!
