Create multiple objects while seeding in Ruby on Rails

I have the following seed file that creates many animals which are then added to the animal_store object

animal_store_seeder:

animal1 = create(:animal)
animal2 = create(:animal)
animal3 = create(:animal)

create(
  :animal_store,
  json: {
    "animals": {
      animal1.id=> {
       }, 
      animal2.id =>{
    }
   ... 
  }
}    

So far this works. However, I want to create a store with at least 20 animals. I don't think creating each variable is the correct way to go. Is there a better way to instantiate more animals and adding them to the animal_store without having to create them one at a time?
